" Optimus, I've pinpointed the location of Megatron's Space Bridge. High in Earth's orbit." Ratchet explained. "Out of our reach." Optimus pointed out. Arabella was sitting on top of Bumblebee's shoulder, same with Raf as well.

"Ok, so you guys don't fly but can't you just ground-bridge there or Arabella could do a spell or something?" Miko asked. Ratchet grumbles annoyed. " The Ground Bridge has limited range. Stretch all the way into orbit its vortex could snap. And scatter us to the stars"

" Even my spells couldn't reach to space as well" Arabella added.

" Since Megatron is likely already in transit, I'm afraid we must take that risk. Reaching the Space Bridge first is our only means of stopping him"

"Hey, guess who's back! " Arabella smiles to see Arcee and Jack, " Nice seeing you again" Arabella replied which he smiled back.

" Autobots, prepare for departure" Optimus ordered which Arcee and Jack looked confused. "Where to?" Arcee asked.

" The final frontier" Miko answered, " Space? I thought they didn't have any way to get there" Jack asked confused.

" They don't, really" Raf said as Bumblebee gently places him and Arabella on the ground. The young witch gently pats Bee's pedes which he replies with a happy chrip.

" Be seen you?" Jack said to Arcee which she gave him a smile and a shrug before joining Optimus.

"Be careful, 'Bee" Raf said to his guardian which he beep to Raf in reassurance. Miko approached Bulkhead. " I'm so jealous" she exclaimed

" Don't even think about following me" Bulkhead warned as Arabella chuckled. She ruffles Miko's hair. " Don't worry Bulkhead, I'll keep an eye on her" she reassured the wrecker.

" Come back safely Optimus, everyone" she said as Arabella places her hands on his pedes which he sends her a small but warm smile to her.

" Optimus, if you leave me stranded on a planet teaming with humans, I will never forgive you" Ratchet vowed.

" Until we meet again, old friend." Optimus told Ratchet as he activates his face mask." Autobots, roll out!" Optimus and the others transform into their vehicle mode and speed through the ground bridge.

Ratchet opened the communication transmission as Arabella and the other kids listened to what was happening.

" It appears the Decepticons have sustained serious damage to their interstellar navigation system"

" Uh, that's my handiwork." Bulkhead told Optimus,

"Great job, Bulkhead" Optimus praised the wreaker, "Without the dish, Megatron would be unable to aim the Space Bridge at Cybertron."

Arabella felt her magic warning her about something to which she agreed. " I hate to say it but it feels too easy, I feel like Megatron has something in store" she said, earning confused looks from the people in the base.

Arabella looks at Ratchet and then at the computers. " If the Autobots are able to use human technology... the Decepticons could do the same with their own ill intent" she explained, Raf eyes widen, realizing what she meant.

" The giant sized array of satellites in Texas" Raf exclaimed, catching on to what Arabella meant.

Ratchet shushed them "This is not child's play." he exclaimed as Arabella deadpanned at her guardian.

" Good thinking, Raf, Arabella. Ratchet, have agent Fowler alert the array staff to the security hazard." Optimus ordered.

Everyone jumped to the sound of someone shouting." You, soldier! You on the uniform! Put on some pants!" he groggily shouted before passing out. Arabella slap her forehead, embarrassed by her godfather.

" That may be a challenge" Ratchet commented as Arabella agrees with her guardian.

" I gave him some healing potions but they take a while so yeah, my godfather is out of commission" Arabella said as well.

Raf starts typing on the laptop. " I can't get past the array's firewalls. They're too thick"

" You actually think you could keep the Decepticons out?" Ratchet questioned Raf .

" Maybe, if I could get in" Raf answered which Jack walks towards him. " W-wait, Raf, what if we could get you all the way in? Like 'inside-the-building' in?" he asked, Raf nods his head to his idea.

" I could log into their intern network on the other side of the firewall." Raf said as Optimus shot down the idea. " The risk is too great, the Decepticons would be there. Perhaps even on sight"

" Optimus! We can't stand here and do nothing. All I'm asking you is to put faith in us that we can succeed in this" Arabella voiced out, as Jack backed her up. " Optimus, with all due respect, you said it yourself, this is bigger than the safety of three humans." Jack said.

" Yeah, if we let the 'Cons win, we are fragged, along with everyone else on our planet" Miko added as Optimus asked Raf for his opinion.

" I wanna give it a shot" Raf confident said.

Optimus agreed as Ratchet sets up the ground bridge to Texas. As Arabella was about to enter, Ratchet spoke which surprised her. " You're one of the only humans I tolerate so come back safely" he muttered but Arabella caught onto his words.

" I promise I'll bring everyone safe and stop the Decepticons as well" she promised as everyone entered the vortex.

Jumping out of the ground bridge, Jack, Miko and Raf groan in discomfort beside Arabella. " That would take some getting used to, how come your not affected?" Jack asked her which she shrugged.

" As I said before, apparition is a lot worse. It feels like being forced through a very tight rubber tube" she explained as the kids imagine themselves in the scenario which they shuddered. They spot the building and head towards the door, Jack tries to open the door but doesn't budge.

"It's locked" Jack said as Arabella pulls out her wand and tapped on the door handle which opens. " Magic. Why am I still surprised?" Jack mumbles as Arabella smirks and playfully rolls her eyes.

They managed to find the control rooms, " I'm in. And so are the Decepticons" Raf said. Arabella held her wand tightly as she keeps her guard up.

" Schematics. With the same alien math we saw on their ship. But this time, I can download it" Raf said as he hacks into the database.

" They're locked on to Cybertron, but not for long" Raf begins to take over the controls unaware of Soundwave watching them, Arabella spots a security camera which slightly turns to them. Arabella shoots a spell that disables the camera, leaving a slightly surprised Soundwave.

" The dishes are heading back towards Cybertron. I won't let them do that again" Raf explained. " What happens when the 'Cons realize they are been punk?" Jack ask.

" It's only virtual combat, you know, like online gaming" Raf explains as Miko comments. " Yeah, Jack, what are the 'Cons gonna d-" Arabella sees robotic tentacles behind them. " WHAT OUT!" she screamed as Jack and Miko were grabbed.

" relashio " Arabella shouts as the tentacle forcibly releases Miko and Jack as she continues to shoot stunning spells at it. " Raf, it may be a good time to do something now!" she yells.

" I won't let them lock on again" Raf says as he managed to download the information in the USB but a tentacle tries to strike him down but stops as it slithers back away from the kids.

Everyone rushes to the doubles door where they see a thin, purple decepticon. It turns around and spots the children but zooms closer to Arabella's face. Miko takes a picture, same with the purple Decepticon and has the video of Arabella performing magic.

Arabella shoots spells towards it but it dodges it as it flies away. " Why is he leaving?" Miko asked as Arabella and Raf noticed the wires cut.

" He has cut the hard-line. The dishes are locked onto Cybertron. For good " Raf grimly explains.

" We need to head back to Ratchet now! You guys remember how I mention apparition" she said as the others nodded. Arabella grabbed Jack and Raf's hands as Miko grabbed Jack's, " You guys might puke after this" she sheepishly said before the others could say anything, they already had apparated.

All three of them felt the sensation of apparating, like how Arabella described it as going through a tight rubber tube. All they screamed as Raf held tight to Arabella's arms, afraid to let go as Jack gripped her hand, same with Miko.

They popped at the base, succeeding in making Ratchet jump in fright. " SCAP! WHAT THE FRAG?!" he yelped seeing the slightly green kids beside Arabella.

" No offense Arabella but never do that again" Jack said as he almost gagged. Arabella pulls out three potion bottles from her extension charm bag and hands it to Jack, Miko and Raf. " Here drink and it will immediately make nausea go away" she explained.

All of them drink the potion as they become better. " This is incredible" Raf awed. " Thanks, Raf but we go bigger fish to fry" Arabella says as they head to the computers near Ratchet.

"Optimus! I'm registering a rapidly expanding mass in their Space Bridge vortex. One with a peculiar energy signature" Ratchet informs as Arabella notice Fowler walking over which she supported him, he gave a thankful expression to his goddaughter as they watch the screen.

" Dark Energon. " Optimus concluded "Ratchet, we must destroy the Space Bridge. There's enough live energon cursing through it to achieve detonation. But we lack the firepower to ignite it."

" If I knew how the Space Bridge was engineered, I might find a tactical way of accomplishing that feat" Ratchet explained.

" Hm, would schematics help?" Raf asked as he shows the USB to Ratchet.

" Optimus, I must say the Space Bridge is our sole hope of ever returning to Cybertron. Are you certain it's destruction is the only option? " Ratchet sullenly asked.

" I am afraid so" Optimus replied.

" Then by all means let us light our darkest hour" Ratchet announced, Arabella prayed that they would make it.

"These things are getting closer. That's bad, right? " Fowler pointed out the computer screen of more cybertronian zombies number rising, " Yep" his goddaughter replied. "Ratchet, we're in position" Arcee commed,

"Arcee, pay close attention." Ratchet warned. He instructed the instruction to Arcee how to blow up the space bridge which they succeed.

"Yes! Right?" Fowler shouted as the kids just stared at him while Ratchet sets up the ground bridge.

" Optimus, the Ground Bridge is ready and waiting" Ratchet said as Arabella hold her breath, hopping they would make it.

Everyone waited for the others to arrive, Arabella breathes out in relief as she spots the familiar red and blue bot. Her godfather rubs her back in comfort, knowing how worried she was over the Autobot's safety.

Miko runs to her guardian and hugs one of his digits, Bumblebee carries Arcee's limp body as Jack walks over to his guardian.

The mood goes dark when seeing Arcee's body"We lost one this week, by the Allspark, don't let it be two" Ratchet prayed, Arabella walks forward, and everyone looks at her.

Arabella pulls out her wand and whispered " Rennervate! " which a light, green trail emits from her wand as it wraps around her body. Everyone watches amazed at the display of Arabella's magic, it felt somehow warm and safe as the light fades.

Arabella encouraged Jack to see her which he gently hold Arcee's servos. Arcee slowly opens her optics and sends a weak smile. " Jack, really? There are other motorcycles in the world"

" But you're my first" Jack softly replied. Arcee looks at Arabella and thanked her.

" I wouldn't want Jack to be lonely without his partner" Arabella gently said as Jack and Arcee smiled back at the girl.

" And Megatron? " Ratchet asked.

" Not even he could have survived ground-zero" Optimus replied which Arabella walked over to her godfather and nudge him, which he nodded. " Prime! I didn't get to thank you, 'Bots, for the save. I owe you one. We all do." Fowler thanked them before hugging his goddaughter and leaving the base.

Miko walks to Optimus "So is this the part where you say goodbye and tell us we need to forget we ever saw you?" she sadly asked which Optimus looks at them, saying that they will protect them still which Arabella smiles at the leader, knowing that coming to Nevada Jasper was worth it and can't wait for more adventure with her friends and the Autobots.

A/N: Now Soundwaves knows of Arabella's magic, what will happen to her?

For the next couple of chapters, I need a name for a Scraplet, any suggestions?
