Arabella was looking for her phone. Jack and Raf were surprised to see her whole arm sticking in her bag pulling out the most random items but what shocked them the most was that she pulled out a whole broomstick which Ratchet dropped his datapad from witnessing.

" How hard is it to find my phone?" she grumbled as she dug deeper into her bag. Instead of her phone she pulled out a glass spinning top device which was sneakoscope, she had forgotten about it, it was a gift from Fred and George from Egypt.

Arabella saw Miko sitting on Bulkhead's shoulder talking about going to a monster truck rally. Ratchet picked up a signal  " Optimus, I'm receiving a signal from a restricted band. It appears to be coming from a starship in this solar system " Ratchet explains as everyone looks at the screen. " It's an Autobot identification beacon "

' So there are more Autobots out there" Arabella thought. 

" The masses were scattered across the galaxies when Cybertron finally went dark " Arcee answered, " But cons have been known to bait traps with false beacons" she frowned as everyone's attention was on the screen.

" Uknown vessel, this is Autobots outpost Omega One. Identify yourself" Optimus commanded. Statics can be heard from the speakers, " I've had warmer welcomes from the Decepticon combat brigades" the male voice told. 

Bulkhead perked up to the voice, " Wheeljack?!" he exclaimed, " You old con crusher! What are you doing all the way out here?" the wrecker asked.

" Bulkhead? That's you? What's with all the security?" Wheeljack questioned.

" The rock we're on is crawling with cons. How soon can you get here and even the odds?" Bulkhead asked. " Sometime tomorrow by putting metal to the pedal," Wheeljack answered.

" You seem really excited about this huh," Arabella said, smiling as Bulkhead nodded excitedly. " Another bot is coming here! How cool is that" Miko exclaimed.

" Wheeljack? I know him by reputation only" Optimus said as he looks at Bulkhead, " Can you verify his voiceprint?"

" He is 1000% the real deal Optimus" Bulkhead clarified with his leader. " We will send landing coordinates, Wheeljack. Safe journey" Optimus informs.

" See you soon buddy!" Bulkhead chimed, " I'll make sure you get a proper welcome " as the transmission ended.

Arcee walked over to Bulkhead as Arabella leans on the rail to listen, " So who's the boyfriend?" she asked. Bulkhead chuckled as he answers the femmes question, " Me and Jacky go way back, we were part of the same war unit ' The Wreckers' which means the cons gonna wish he never found us "

Arabella quietly laughed watching the excited wrecker see his friend. This made her think of her friends at Hogwarts, and how she missed them.

The next day, everyone was watching the screen, Arabella standing with the other kids. " Wheeljack ship arriving on the landing zone" Arcee announced as everyone watched the screen.

" Do you think he's here to visit?" Raf asked the older teens.

" Maybe he'll stay. Hm have to find his own human though or..." the pink streak-haired girl looked over to the witch. " Sorry, Miko but I'm Ratchet's charge" Arabella said. Unknown to the others, Ratchet subtly smiled as his cheeks slightly became tinted but he shook them away, focused on typing.

" Ground bridge cycling up" Ratchet announced but the machine burst into sparks which the medic banged the computer. " Blasted scraplets! Equipments hasnt been the same since the infestation"

" So Wheeljack's gonna land halfway across the world and you'll bridge him here?" Arabella asked as Optimus turned to the brunette witch. " We can't risk revealing the location of our base, just in case the Decepticons are tracking Wheeljack ship" 

Arabella watch Miko running up to Bulkhead who was pacing excitedly. " Dude I've never seen you so stoked " Miko exclaimed.

" Oh, you're gonna love Wheeljack. We were like brothers and tonight we're gonna party". Bulkhead and Miko cheered which brought smiles to everyone's faces. Alarms interrupt the warm atmosphere as the screens show Decepticons following Wheeljack.

" Bogeys! closing fast from Wheeljack position" Arcee points out, Bulkhead growls at the screen, " Con scum!" as the Autobots wait for the groundbridge.

" Open the bridge Ratchet! We're missing all the action!" Bulkhead exclaim as the medic activates the ground bridge. " I'll prepare sickbay" Ratchet says but Bulkhead chuckles, " Who for, the cons? This is Wheeljack we're talking about" as Arcee, Bumblebee and Bulkhead rush inside the ground bridge.

As the others waited for the other's return, Arabella went back to find her phone in her bag, leaving out the broomstick and the sneakoscope. Raf picks up the magical device as Jack examines the broom. " How do you fit all this stuff in your bag?" the raven hair teen asked.

" I used an extension charm for my bag " Arabella explains as she huffs annoyed that she still couldn't find her phone. The sound of the ground bridge caught the teen's attention as they saw the Autobots and Wheeljack heading inside the base.

The machine sparks as Ratchet sighed annoyed by the damage. Bulkhead introduced Wheeljack to Miko as Optimus appeared. " Optimus Prime, it's a privilege" Wheeljack greeted the Autobot leader.

" Likewise soldier, what have you reported from your long journey?" Optimus questioned.

" Been bouncing from rock to rock, searching signs of friend or foe. Now I find both" Wheeljack answered but a loud clicking sound echoed the base as all eyes and optics were on Arabella, holding a strange object.

 " Sorry about this, it's an old device" she mumbled as it kept on spinning and lighting up near Wheeljack. The witch furrowed her eyebrows as her eyes widen to the realization, that she remembered that a sneakoscope can indicate a threat or someone untrustworthy. She looked at Wheeljack as he gave her a confused expression but shrugged it off.

Optimus continued speaking, " We are few but strong. We have suffered losses but we have grown and we would relish welcoming  a new member into our fold" 

" I would be honored," Wheeljack said,

 " Well let's get this party started " as Bulkhead and Wheeljack started to mess around. Arabella watched Wheeljack cautiously, the sneakoscope still in her hand, something about Wheeljack didn't sit right with the witch.

" Oh joy " Ratchet grumbled as Arabella sent her guardian a sympathetic look towards him which he replied with a small smile. 

Soon, Miko brought out her guitar and started playing. Arabella was with Ratchet as she wearily looked at Wheeljack messing around with Bulkhead with a metal ball. 

" So what's that about?" Jack asked, " It's called lobbing, the favorite pastime on Cybertron, especially upon the warrior class" Arcee answered as they both watch both wreckers throw the lob ball around.

Miko asked Raf to dance which he and Bumblebee started to dance which Arabella cheered.

 " Where Optimus?" Jack asked.

" Went for a drive. Primes don't party" Arcee said as they both continued to watch the two wreckers.

 Arabella was actually offered by Optimus if she wanted to join him. She politely declined his offer, still suspicious of Wheeljack. 

Bulkhead threw the metal ball at Wheeljack but missed as it hit the wall and was about to fall to the witch and the medic. Arabella waved her wand and the ball froze in mid-air. Ratchet released a breath as he gratefully looked at her before glaring at the other two.

" You know what, I am attempting to perform sensitive calibration here!" Ratchet exclaims at the two wreckers as Arabella placed the ball on the ground.

Wheeljack got over his shock as walked toward the both of them, " Sorry doc, guess we're a little charged" he apologized but looked at Arabella. " I didn't get your name?" he asked as the brunette witch subtly gripped her wand.

"  Arabella Scamander " she introduced, as her brown eyes clashed against his blue ones. Wheeljack leaned closer at her, smirking while eyeing her but focused his attention to the medic.

 " You built this bridge from scratch huh?" Wheeljack ask Ratchet. 

" I did " Ratchet answered.

"That's quite a feat of engineering" the tri-colored mech complimented

" Yes, it is. " Ratchet said. " Something wrong with it?" the tri-color wrecker asked/

The witch raised a brow at Wheeljack, he was asking a lot of questions about her guardian which sent red flags in the witch's mind.

 Ratchet merely glanced at Wheeljack, " I didn't care for the way it sounded this last jump. I put it in shut-down." as Arabella subtly gripped her wand, her instincts plus magic putting her on high alert.

" So, uh, how long will the defrag take?" Wheeljack now facing the medic as the witch's brown eyes clash against his glowing, aquamarine optics.

" A few hours, if we're lucky. M-maybe longer " Ratchet looked at Wheeljack then back at the computers as the witch let out a sigh of relief when she saw Wheeljack head back to Bulkhead. Ratchet caught sight of her stressed expression but didn't question it.

Soon Arabella was with the others, sitting on one of the crates, listening to Bulkhead's adventures. " So there we were ... No communications, low on energon, surrounded by cons. So, what does Wheeljack do? " he turns to Wheeljack expectantly "Tell them, Jackie."

Everyone looks at Wheeljack expectantly but he stood silent for a second before replying, " Well What I do best" he said non-shurlunctly.

" He chucks his only grenade smack into the primary heat exchanger" Bulkhead exclaims, laughing. " Yeah, seemed like a good idea at the time" Wheeljack added in.

" The joint went supernova! " the green wrecker finishes as he throws his arms into the air. Miko awes at her guardian " Awesome!"

Bulkhead grins at the others, "Yeah, I'm still picking shrapnel out of my backside" as he scratches his back.

" I'm not surprised given the size of your backside " Arcee comments as Bumblebee laughs which made the brunette witch smile a bit but keep her eyes on Wheeljack. 

The white, red, and green bot glanced at Ratchet who was typing up on the screen. His optics narrowed but no one noticed it but Arabella did.

Arabella was looking down at the sneakoscope, which was still pointing towards Wheeljack, not realizing that he was gazing at her. " There it is, Jackie's signature - One grenade, one shot." Bulkhead was saying but noticed his friend's expression.

" Hey, you all right? " he asked in concern as Wheeljack optics finally pulled away from the human witch, " What?" 

" You don't seem like yourself " Bulkhead said as Wheeljack stood up, facing him. " Well, what do you mean?" Wheeljack asked.

" I don't know. You seem quiet." the green wrecker replied. 

" Aw, I've been stuck in a can too long." Wheeljack lied smoothly, "I should go topside before I get stir-crazy"

" I have patrol in the morning " Bulkhead said. " You can come with " he adds in.

" Lets go now " Wheeljack suggests. " And break up the party? Come on! The gang's loving you! You got to tell them about the battle of Darkmount Pass! You tell them. "  Bulkhead said excitely.

" You're better at it."  the white bot said as he looked down at the girls " How about if Miko and Arabella show me the rest of your base?" he asked.

Bulkhead looked surprised " Well, yeah, sure, Jackie."  as Miko hops off the crate getting ready for the tour.

Wheeljack looks expectantly at Arabella but the witch shakes her head, " I need to fix this device but I'll join later" she smoothly lies, earning a shrug from the Japanese girl and a tiny frown on Wheeljack's faceplate.

" Do you play any instruments? Can you fly? Have you thrashed more Decepticons than bulkhead? " Miko asked the wrecker as both of them walked away.

Bulkhead stares in their direction concerned, along with Arabella. " You all right?" the witch asked as the green wrecker stared down at her form. " Yeah, just Out of sorts, I guess. 

" Don't tell me you're jealous" Arcee slightly teased. " That Miko's making a new friend? Come on. Something ... something's just not right about Wheeljack." 

" Bulkhead, really? He's traveled galaxies. You haven't seen him for centuries. He could just be rocket-lagged or Well, bots do change, you know?" Arcee tried to reassure the green wrecker.

" Not Jackie" Bulkhead said.

" Actually I have to agree with Bulkhead with this one" as all eyes and optics were on her, she continued. " What I'm holding is a Sneakoscope. It's a magical device that activates if someone was doing something untrustworthy nearby" emphasizing the machine pointing and whistling in the direction where the duo headed off.

" Before you think this device is faulty or broken, it has saved me and my friends many times so take it from me personally... this device does not lie" she warned as her words swirled in their processors. 

Arabella decided to stalk behind the tri-color wrecker and Miko as they continued their tour. " Energon stockpile, power generator, armory... Everything you need to blow the joint sky high" Miko says as Wheeljack looks around the place.

" Where's this bunker located exactly?" Wheeljack asked as Miko darkly look at the wrecker, " If I told you, I'd have to rip out your spark chamber." she warns.

Wheeljack looks at her unfazed, as Arabella gets ready to intervene. " Kidding! Just outside Jasper, Nevada, though I don't expect that to mean too much to you"  she casually says as she continued to walk.

" Can't say it does. So, uh, any way out of here besides bridging? " Wheeljack asked.

" Why?"

Miko let out a surprised yelp as Wheeljack jumped slightly as both of them turned around to find Arabella behind them, the light shining down on her body. 

" You're not planning to leave already, are you?" Miko asked as Wheeljack's attention was back to her. Her face changes to a smile, " Come on. I'll show you " 

" Arabella! Whatcha took you so long?" she asked as Arabella walked beside the pink streak girl, " Just needed to do something" she simply said as she walked backward, facing Wheeljack.

The bot raised his optical ridge at her but she noticed that his optics held an interest in her. " So, wanna tell me that trick that you did earlier?" he asked.

Miko answered his question, " Arabella here is a witch, she can do wicked spells and magic. It's awesome!" 

" I see," he said as they headed back to the command center. The trio saw Bulkhead arguing with the others. " Hey. What are you guys talking about?" Wheeljack asked.

"I was just telling the guys all about you and me at the battle of darkmount pass." Bulkhead said as he gave a knowing glance at the witch which Arabella nodded, sticking close to Miko if something happens.

" That's a heck of a story " Wheeljack said. " Yep. Tell it." Bulkhead glared at ' Wheeljack'. Miko interrupts the conversation, "Talk, talk, talk. How about after we go off-roading?" she asks.

" Miko! Stay out of this! " Bulkhead warns as Arcee walks forwards " Bulkhead, easy."

Wheeljack nervously looks at the blue and pink femme,  " I'm not sure I ..."

" As Bulkhead's best friend, it shouldn't be a bloody chore to explain the story now unless ..." Arabella trails off, daring him to finish the story which Bulkhead glances at the witch than at Wheeljack.

The bot glares at them both, " Fine. You want to live in the past, bulkhead? The wreckers were trapped between a Decepticon patrol and the smelting pit. The cons were vicious, bearing down on us with everything they had. Me and bulkhead engaged the enemy, left them for scrap, then I made us a way out using their backsides as stepping-stones to cross the molten metal" he finished explaining.

" Isn't that how it happened?" he asked.

"  Yeah. That's exactly how it happened." Wheeljack gave a smug look. "Except for one little thing..." Bulkhead added that Wheeljack's faceplate changed into shock as Arabella smirked a little, knowing that the metal weasel have been caught.

Everyone looked at the two of them shocked, ' Wheeljack's' face changed into anger, the witch slowly getting into a defensive position to protect her friends.

" I'd already left the wreckers to join up with Optimus, but you wouldn't know that if all you did was access wheeljack's public-service record."

" Bulkhead, what does that have to do with -- Ahh!" Wheeljack was about to grab Miko but a blur of brown pushed her out of the way and now Arabella was in the fake Wheeljack's servos.

" Arabella!" everyone yelled, "Stay back, or I'll squeeze her into pulp" the fake bot threatened as the witch tried to get out of his gripped or tried to reach her wand. Bulkhead glared at the bot in front of him.

" Wheeljack, what are you doing?" Miko yelled as the boys pulled her away from the danger. " Decepticon coward! Let the girl go and face me! " Bulkhead yelled. 

"Don't fret. Plenty of fighting to come." the fake bot replied.

"Is there a real Wheeljack?" Jack asked, terrified for his friend's safety. Ratchet gritted his teeth, seeing his charge at the hands of a Decepticon.

" Oh, indeed, and I expect lord Starscream is making sport of him." he evilly smiles as Bulkhead glares at him but worries over Arabella's safety. Soon the Decepticon sees the defrag system finishing and activates the ground bridge.

" Let's get this party started." Noticing the bot distracted by his short-lived victory, Arabella could faintly brush the end of her wand before grabbing it. 

" Lumos " she yelled as a bright light pointed at his optics. Yelling in pain, he let go of the girl, free falling to the cement ground. Bumblebee dove towards the ground, softly catching her frail form.

The witch gratefully smiled at Bumblebee before focusing back on the fake bot. Before the Decepticon could do anything, the real Wheeljack kicks the bot in the back as the Decepticon is sent flying towards the wall.

Bee gently puts down Arabella as the humans face the real Wheeljack, " I'd shut that hole before the stink comes through"

Soon the fake ' Wheeljack' wakes up and both circle each other, as everyone watches them. Bulkhead bashed his fist together, wanting revenge for fooling him and especially what the imposter did to Arabella but his real friend stops him, " Ugly's mine" 

Soon they begin fighting, the others losing track of who is who but the real Wheeljack got the upper hand and defeated the fake one.

" That's my Jackie " Bulkhead said proudly which Wheeljack sheth his blade and retract his face mask. " It's time to take out the trash" 

" Wait! There's one thing I'm actually curious about" the witch said as everyone watched her approach the defeated bot.

" Revelio " she pointed the wand at the fake Wheeljack which slowly his white, green, and orange paint job changed into black. His frame started to change as spikes started to form around his body as his eyes revealed a once electric blue to a glowing yellow.

" You managed to reveal my true form. How interesting, the Decepticons would love to know about your gifts fleshy" he weakly growled.

Ignoring his comment, she looked at the wreckers, " You like explosions right? How about you send him off in a wrecker style" as a devious smirk etched her face. Wheeljack and Bulkhead smirked along with her, " I can tell I already like you doll" he said.

" All yours, buddy." As Bulkhead approached the bot and activated a bomb on him, ' I sounded like a Slytherin, Daphne would be proud of me" she sweatdrop at the thought.

Soon everyone watched as Bulkhead threw the fake bot like a rag doll through the bridge, Arabella whistled at his good throw, " Nice lob " Wheeljack complimented as he looked at Arabella, " smart idea doll" he smirked which Arabella copied back, ignoring the blush on her cheeks, " Nice dance moves you had there" referring to the sword battle.

Soon everyone beside Ratchet and Optimus was having fun, the witch was dancing with the others. 

Arabella decided to take a break from dancing and walked towards Optimus, Ratchet, Bulkhead, and Wheeljack on the other side.

"It's like a recurring nightmare." the medic groaned as Arabella shook her head, amusingly. " Now that you're part of team prime, we need to pick out a vehicle mode for you. I have some ideas" Bulkhead excitedly said to his best friend.

" Uh, about that, bulk -- Now that my ship's repaired, I'm itching to know what else I might find out there " the tri-colored bot replied.

" Wait. You're leaving? Why? " Miko asked as the others ran up to him.

" Because some bots never change" Bulkhead answered as he smiled soon everyone copied him.

" Wheeljack" Optimus began "Know that you'll always have a haven here" Bulkhead side hugs his friend, " Jackie never stays, but he always comes back"  he grins as they both fish bump each other.

Everyone is outside, seeing Wheeljack off. " There's room for two, bulk, even with a backside like yours. Who knows who we might find out there -- Some of the old crew? " Wheeljack asked.

The green wrecker considered for a moment, before looking at Miko, who looked sad at the thought of her guardian leaving him then he looked at the witch who softly smiled at him.

" Heh. It sounds like fun, Jackie. But my ties are here now with them. With her." Bulkhead replied as Miko beamed at her guardian.

Wheeljack nods, " If anything happens to my favorite wrecker, I'm coming after you " he playfully warns as he looks at Arabella and smirks at her, " You too doll " he winked.

"I'll take good care of him." Miko pulled out her phone, " Now, say "cheese." snapping pictures of both of them. Soon, the others watched Wheeljack'ss ship disappear higher in the morning sky.
