Arabella was with Miko, Jack, and Raf arrived at the Autobot base, which was the weekend for the kids, much to Ratchet's disappointment.

Miko got out of Bulkhead vehicle form as Arabella caught a ride with Raf. " Race you to the game controls " The witch hopped out of Bumblebee's car form and she let out a tired yawn, she just finished preparing the Animagus potion and was one step ahead of becoming an animagus.

Arabella watched Jack and Miko play a racing game that the Japanese girl won three times in a row. " Arabella, why don't you and Raf have a go? "

Standing up, she felt sudden dizziness and slumped back onto the couch, clutching her head in agony. Waves of nausea hit her like a truck.

"U-Ugh...what in Merlin...?" She groaned. Her sight was blurry and her brain was pounding wildly. " You okay Bella? " Raf asked, noticing how ill she looked.

" I'm Fin-A-ACHOO!!" she sneezed loudly, capturing everyone's attention. Arabella's eyes started to flutter shut as her body swayed before collapsing to the ground.

" Arabella! " the three kids cried out as they rushed to her fallen form. Jack placed his hand on her forehead, " Her head is burning up "

Ratchet wasted no time in carefully grabbing the witch and placing her on a medical bed in the med bay.

"Mhmm..." she mumbled out loud. Slowly, Arabella opened her eyes to see a blurred ceiling above her.

"What the...?" she muttered, sitting upright as she tried to get her bearings back. " What happened?" she said, wincing a little. Her throat was sore and she felt uncomfortably warm.

" Here you need to drink this " Ratchet somehow handed her a plastic water bottle in his giant hands. Downing the liquid in one go, she sighed in contentment as she felt it quench her parched lips.

"Better?"

"Absolutely." She offered a weak smile.

" Now you must rest, you just have the flu so I asked Jack and Arcee to grab some human medicine for your illness "

" But I can't, I have to feed my creatures and clean up my suitcase ... " Arabella tries to stand up but Ratchet's fingers gently pressed her down on the bed.

" Hush, you need rest in order for you to recover, " Ratchet said, concerned over her health.

" We can help you with your chore, it beats doing nothing in here " Miko cheered, excited to head back to her magical suitcase again. Raf nodded, he wanted to help Arabella and at the same time visit the magical suitcase again.

Arabella sighed but knowing that she wouldn't be getting any better soon and her healing potions supply ran out, she twirled her finger. A feathered quill and parchment appeared, already scribbling down.

" I'll send chores for you guys to do for the gentle and harmless creatures which should all be on the list "

The quill finished writing as the parchment flew toward the kids. " Just make sure to avoid the dangerous places, I put charms there so only I can enter," she said.

The Autobots had become human-sized thanks to Ratchet's device which was secretly inspired by Arabella's shrinking spell that she did on them the last time. The brunette witch and medic watched the others enter the suitcase.

Optimus decided to stay at the library, organizing the slight mess. He noticed one of the books moving and cautiously held it in his hand, it was growling and wriggling out. Remembering what Arabella's instruction said, he gently stroke the spine of the book which it purred before opening up.  

He soon became fascinated with the magical knowledge of the book, full of information about the magical beasts. He even recognized some of them from the ones he encountered and remembered the conversation with Arabella when talking about them.

The other Autobots were doing their separate chores," Hey buddy, remember me " Bulkhead cautiously approached the Ironbelly which the dragon beamed seeing the familiar face. 

The dragon's long tail wagged excitedly as Miko squealed in Japanese about how cute the dragon was.

" Okay so Arabella wanted to feed you and clean up the den " Bulkhead read the list, it wasn't particularly messy, only ashes and meat bones that needed cleaning up.

" It will be a piece of cake and Arabella would be impressed, you would like that huh Bulk " Miko teased which Bulkhead jumped and faced his charge shock and embarrassment before quickly sweeping the ground to hide his blush. 

He didn't forget when he and Arabella were flying on Snuffle, he still could remember how her hair gently danced in the wind and how her smile made his spark fill with warmth.

The Moon's calves were already jumping up and down excitedly seeing Raf and Bumblebee carry the bucket of food for the bug-eyed creatures.

" Aren't they cute Bee? " Raf asked which the yellow and black scout whirled in agreement. Under his mouthguard, he couldn't let out a soft smile, ever since Arabella came into their lives, it's only been a magical and fun adventure, learning about magic and becoming friends and allies.

He couldn't get Arabella's smile and her charming personality out of his processor a faint blue blush appeared on his faceplate.

 Raf looked up at his guardian, " You have a crush on Arabella don't you? " it didn't take Raf much to figure out, especially seeing Bumblebee stare or daydream about the witch.

Bee almost dropped the bucket and stared at Raf with wide eyes, " : I-I don't know what you talking about... : "The poor mech rambled on his whole faceplate erupted in a bright blue now.

" It's fine Bee and I think you guys would be great together " the younger boy innocently said, he could imagine Bee and Arabella together. 

Bumblebee looked at his charge shocked, ' So Raf doesn't mind me having feelings for Arabella? ' ever since Arabella introduced herself and became friends, he couldn't admire her and her love for magical creatures.

Bumblebee wasn't the only one having these thoughts, Bulkhead,  Optimus, and Ratchet were having similar thoughts as well.

Arcee and Jack were busy feeding the Occamy's, " Have you noticed the others acting strangely around Arabella? " Jack asked his guardian, to his surprise the femme chuckled.

" You just noticed now, to be honest, I'm surprised how Arabella doesn't realize it yet, " Arcee said, she knew that her team had feelings for the witch. 

 " Honestly I think Miko, Raf and I have been noticing them, don't you humans have this thing called ' crushes ' in relationships? " she hinted towards her charge.

As if a light bulb lit up the raven-haired head, " Wait they all like Arabella?"

" Even Optimus? " he didn't believe that the stoic leader had a crush on his friend. 

" Even Optimus though you need to spot the signs closely," she said, knowing how intrigued he was about the witch's magic and how his expression softens when she explains magic to him.

" I think that's done, let's head back now " Arcee was climbing out of the suitcase. " Even Ratchet, the grumpy medic who heavily was against humans at the beginning? " Jack asked, still not believing it.

They watched Ratchet having a normal but lively conversation, Jack had his jaw slightly dropped seeing the sight of the happy medic. Arabella was still sick but thanks to the medicine Ratchet provided her, she could hold a conversation with the medic, not knowing the warm smile towards the girl.

" Told you, Jack " Arcee smirked but was glad that her comrades were and hoped for the best for them.

BLOOPER SCENE:

Miko was grinning which slightly creeped Arcee out, the two boys were busy playing video games so it was just the girls including Arcee hanging out. 

The bots were busy doing their own things, Ratchet was busy organizing the med bay as Optimus was reading reports on the holopads. Bulkhead was tossing a small, metal ball in the air as Bumblebee was just sitting on a metal create, relaxing.

" Hey Arabella, please say darling in a seductive way " Arabella looked up from her book, surprised. " Why? " she asked, slightly suspicious of the pink phone in her hand as if Miko was ready to record something.

" Just no reason " Miko smiled which made the witch grow slightly more suspicious of her.

" Hmmm fine ..." The witch was unaware of the bots listening in on their conversation as Arabella lightly bit her lips as put on a seductive face, " Darling " Miko smirked as she pressed the video recorder " Now in three, two ... and one "

That triggered a chain reaction, Ratchet crushed the wrench in his servos, his face blushing blue. Optimus accidentally walked into the wall, leaving a dent in it which made everyone wince.

Bulkhead gawked but the lob ball bounced back and hit him in the faceplate and Bumblebee managed to stumble off the giant crate and landed on his aft.

Arcee and Miko looked at each other with knowing looks, "men/mechs" The Japanese girl recorded the whole thing as the boys jumped after seeing Optimus smashed onto the wall.

" What did we miss? " Jack asked, baffled seeing a blushing medic, Bumblebee laying on the floor, Bulkhead rubbing his face plate and Optimus trying to regain his composure and walking back to his room.

A/N: here's another chapter and the next chapter is going to be the ' witch on the race track ' This chapter is mostly about how bots realize their feelings towards the witch. The blooper scene was inspired by a tik tok that I found :)

After the last chapter, it came down to the final three choices...

1. a dragon ( Ironbelly )

2. occamy

3. a giant owl

So vote for Arabella's final animagus form.
