"Latitude 39. 5, Longitude 116" Raf told them which Bulkhead typed in the coordinates.

" OK, wait here" Bulkhead instructs the kids as he heads towards the ground bridge.

"Aww, don't break up the band!" Miko dramatically cried, disappointed that she can't go. Before Bulkhead leaves, he turns to Jack. " Jack, you're in charge! " he said before he runs off.

" Guess we four have run out the place" he said as Arabella hums before turning to Miko but the pink-streaked girl disappeared. " Ugh guys we have a massive problem" she said.

Jack and Raf look for Miko but Arabella realized and groans in annoyance. " By Merlin..."

" Bulkhead may have not even realized she'd followed him" Raf panics.

" Miko hasn't seen the 'Cons in action like we have" Jacks adds in as well. Arabella took out her wand and glanced at Raf. " The coordinates are the same right?" she asked and the boy nodded. " Their destination is still locked in".

" I'll bring her back, you guys stay here" she gets ready but the boys stop her. " We'll come with you " she reluctantly agreed.

Raf activates the ground bridge as the three of them head inside. They made it to a rocky terrain as they hopped out of the portal. Arabella felt like this was so much more comfortable than apparition but still felt the similar sensation.

" Are your bones vibrating?" Raf asked and Arabella chuckled. " You think that's bad, wait until you try apparition. It's a lot more worse". The three of them look at the ship in shock, which vehicon spots the three of them and points their guns at them.

Arabella stands in front of the boys pointing her own wand at them, glaring at the enemies.

The vehicons start shooting, Arabella summons a shield and starts shooting attack spells at them. Raf and Jack stick behind Arabella as she continuously shoots spells "sectumsempra" she yells as one of the bots gets deeply sliced and bleeds to death.

Bulkhead arrives in his vehicle form. "Get in, now!" which everyone scrambles in. Arabella sits at the front as the others find a seat.

" Thank Merlin" she breathed,

" Thanks, Bulkhead." Jacks said.

" Y-yeah, thanks" Raf thanked as well.

" Wh-what are you doing here?" Bulkhead asked,

" We were worried about Miko. Have you seen her?" Jack asked as Miko popped up from the backseat. "What's she look like?" she mischievously asked.

" You dung brain. I'm happy and mad to see you right now" Arabella exclaims at the girl. Bulkheads drive behind one of the boulders as he stops and opens the door. " Everyone out! And this time, please, wait here!" Bulkhead instructs Arabella was about to get out but Miko held on to her.

Bulkhead drives off with Arabella and Miko inside. It was tight-spaced and dark which thank Godric that she didn't have a fear of the dark or tight spaces. Miko was about to throw up which thankfully Bulkhead opened his chest.

" Thank you Bulkhead" Arabella breathed the fresh air. " Remind me never to do that again" Miko added as both girls climbed onto Bulkhead servos as he carefully lay them to the floor.

A vehicon attacks Bulkhead and Arabella used her body to protect Miko. Both girls hear a hatch opening as more decepticon soldiers appear as they begin to shoot. Arabella puts up the shield spell over Miko.

Bulkhead spots a piece of metal which he ribs off and used it as a boomerang and knocks down all of them. He looks down and sees Miko covered in a vague, shimmering sphere as he picks up both girls. Arabella climbs on his shoulder as Miko is in Bulkhead servos.

More soldiers shoot again as Bulkhead finds the opening hatch. Arabella was getting annoyed with the vehicon attacking them. " That's it! I had enough of these ferrets!" as a powerful blue blast emits from her wand causing a massive explosion. Bulkhead manage to hop in the hole, they were running in the purple-lit corridor.

They spot more vehicons which Bulkhead made Miko slide on the floor. Arabella felt an irked in her head, " These guys keep on coming" she grumbles as she shoots a full Body-Bind Curse at them which they were unable to move which gave Bulkhead a perfect chance to beat them.

Bulkhead picks Miko up and continues to run. They could hear someone running so Bulkhead and Arabella point out their guns and wand which thankfully they ran into Arcee, Bumblebee and the boys.

" Brought the humans huh?" Arcee asked, " You try getting them to stay behind" Bulkhead exclaims as he emphasises pointing to Miko.

"We need to find Fowler and get the kids out of here" Arcee said.

" He's in the brig." both boys said in unison. More vehicons arrived, they start shooting at them, Bulkhead use his body to protect the kids as Arabella and Jack try to drag them away to a safe place. Soon the Autobots defeated all of them and try to looks for the brig

At the graveyard battlefield, Optimus and Ratchet continue to fight the zombie cybertronians. More of the zombies number grows as they slowly start to feel weak as they go back to back against each other.

" This prolonged exposure to Dark Energon is sapping our strength" Ratchet warns,

Optimus doesn't see a zombie behind him which it pounces but deflects from the shield that Arabella casts. Optimus optics widen at the sight of the vague blue sphere protecting them but more zombies pile on top of them. Optimus uses all of his strength to push them away as he helps Ratchet.

" What sorcery is this?" Megatron growled. Optimus was speechless from the cause of the shields when he remembered Arabella casting a spell over them. " Arabella..." he awed but unfortunately the warlord heard the name. " My legion, finish them!" he yells as more zombie cybertronians march towards the two Autobots.

Back at the ship, Arabella and the others head to the one of control rooms seeing the Autobots take down the soldiers there.

" Wait in here" Arcee commanded but Bumblebee protested but Arcee cuts him off. " They're slowing us down and they're easy targets." She looks at the kids ."They'll be alright in here, as long as they stay put" she adds before leaving the room with Bulkhead and Bumblebee.

" That, was intense" Miko commented as Jack looked furious at the girl.

" Was?!" Raf said, as Jack was mad at her. " It's your fault that we're stuck in this intensity. What were you thinking, Miko? " Jack fumed.

" Did I ask you to follow me? " she asked back.

" You wanted us to be a band. Doesn't that usually mean to play together?"

" Well, maybe I decided to go solo" Miko said as Jack scoffs at her word,

"Well, maybe I have some regard for your safety" Jack snaps back. "Oh, I'm sorry, it's your name 'Optimus'? You can leave my protection to Bulkhead, thank you very much " Miko shouts at jack.

Arabella groaned, their arguing is not making the situation better. " Girl, Girls! You're both very pretty...but can you both shut up" she said as Raf was losing his patience as well.

"Stop it! Both of you!" Raf shouts as he walks over to a corner and squads, resting his head on his knees.

Arabella glares at Jack and Miko. " You both need to get your priorities straight" she coldly said, sending a shiver down their spine and guilt.

Arabella walks to Raf and sits down next to him, Raf hugs Arabella as she softly smiles at the young boy, rubbing his back in circles. Miko and Jack join them, " H-hey, Raf, Raf, it's it's OK." Jack tries to comfort the stressed boy. "Yeah, we're gonna be fine." Miko gently places her hands on his shoulder. "Our bots will come back for us." Miko added.

" Yeah, they're gonna take us home" Raf looks at Miko. " How do you know?" he asked her. Jack spots one of the computers. " Hey, Raf, what do you make of that?" he asked which they all spot one of the screen there.

Raf walks down as Arabella follows him. Raf reads the screen as the others join as well. " It's important. Really important." he explains.

"We've got to get this to Optimus" he adds as Miko looks doubtly at Raf. " How do you know it isn't just a recipe for space-nachos?" Miko asked.

" I know math when I see it. And that is one serious equation." he seriously answered. Arabella placed her hands on his shoulder. " I trust your judgment" she said, supporting him.

"Can you download it? " Jack asked which Raf puts down his bag and pulls out a flash drive. "I've got a flash drive. But I don't see anywhere to plug it in. This tech is way alien."

Arabella's ears pick up to someone walking in. They all run to the corner to hide but Arabella sees Raf's bag there. " Accio bag " she whispered as the bag goes flying towards her as she catches it but the vehicon spots them and aim their guns.

" Confundo " she points her wand at it which it confusingly walks around, crashing into the walls. " Miko take a picture" she yells.

"Great idea! Hey, you! " Miko yells which the vehicon tilts its head confuse as she takes a picture of it.

"Not of that! Of THAT! " Jack shouts, pointing towards the screen which she takes a picture of "Go! Go! Go" Jack yelled as everyone escape the room.

The confused vehicon managed to snap out of the spell and follows them. Bulkhead destroy the soldier as the other Autobots arrived in their vehicle mode. Arabella hopped on behind Jack as they ride on Arcee. " I told you to stay put!" she shouts. They all managed to escape the ship and arrived back at base.

Optimus requested the ground bridge as they arrived at the base. Arabella noticed Ratchet holding his arm. Optimus fixed his arm as he added a metal cast over it as he noticed the children around the unconscious agent. Arabella sat down next to him, gently holding his hand as her eyes looked concerned.

" What happened to you guys anyway? " Miko asked.

" We engaged an army of undead cybertronian warriors." Ratchet explained.

" Zombies? You fought zombies, and I missed it? " Miko exclaimed as Arabella sent the girl a disproving look.

" Bulkhead You exercised extremely poor judgment in allowing the humans to accompany you" Optimus scolded.

" It won't happen again, Optimus. - I promise" he said, Arabella knew it wasn't his fault which Miko seemed to get the same idea.

" But it wasn't Bulkhead's fault" Miko defend her guardian. Before Bulkhead could quiet down the girl she took out her phone and showed Optimus the photo.

" Ratchet, have a look. It could be of importance to Megatron"

"Woah, Megatron's back? That's really bad news, right? " Jack asked which Ratchet looks down and furrows his optic ridge in confusion. "I don't understand. "

Miko looked at the photo which was the picture of the vehicons instead. " That's the 'Con who tried to blow Raf away. At least that's what he looked like before Bulkhead rearranged his grill"

"Miko, Raf was almost killed. This isn't a game! When are you gonna get that through your thick skull? " Jack yelled at her.

" Hm we were all almost killed" Miko sassed back." You, me, Raf, Arabella, even them!"

"Well, if this was just an average day with the Autobots then I don't wanna be a part of it. Not anymore." Jack admitted. Arabella knew this is all too much for the normal human being, facing danger was something she experienced as she grew up in a community where dark witches and wizards terrorized their community.

Optimus sympathetically looked at the stressed boy. " Jack, putting you in harm's way was never our intent. However It is no longer the safety of you three that is at risk but the safety of all human kind. We will respect your decision if you wish to leave" Optimus informed.

They hear the ground bridge activate. " No point in long good-byes. Here's the door" Ratchet told the kids.

" Come on, Raf." the young boy looked at Bumblebee then at Arabella unsure what to do, she stood up and walked over to them.

" You know it's not about making the right choice. It's about making a choice and making it right" she said to Raf and gave him a soft smile. Optimus was slightly surprised the choice of her words, it made her feel like she experienced this before.

" I'll be OK, Jack. See you at school" Raf said as Jack looked slightly disappointed in his choice. He turned to Arabella but she shook her head, telling him that she will stay with the Autobots

Jack looks up at Arcee" I know, you don't exist"

"Don't make me hunt you down" Arcee said as everyone watched him walk into the vortex, Arabella could see the disappointment and upset over Jack's choice.

Arabella couldn't stand still so she asked Arcee for his address which she did. She apparated over to his home to see him fixing his cycling bike wheels.

" Now I understand why you had to rush home" she spoke up which Jack jumped in surprise and dropped his wrench.

" Sorry for scaring you" she picked up the wrench and gave it to him.

" Thanks" he mumbled, resuming to the wheel. " Why are you here Arabella?" he asked.

" I'm not here to force you to come back with me but I do wanna talk to you" she said as she grabbed the spare chair and sat next to him.

" You know out of all the places I wanted to explore, this place first came to mind" Jack looked at her in disbelief. " To Jasper, Nevada. The entertainment capital of the world?" he deadpanned and Arabella shakes her head.

" Yeah, well, the brochure lied. Taking care of a Flobberworm was starting to look pretty good in fact. But then, the last couple of days happened."

" Do you have a point? "Jack asked which Arabella nodded.

" You bet. I saw what you did today. When you saved Raf, Miko. When you came to save us." she said as Jack looked surprised but changed to a slight scowl.

" I've been raised to be responsible. To my schoolwork, to my mom, my job" he responds back. Arabella stands up and walks over to him. " You know someone once told me that the best of us sometimes eat our words but we must all face the choice between what is right, and what is easy" she said as Jack was silent, thinking about what she said.

Arabella sighed, " Goodnight Jack" she said as Jack heard a pop sound and found Arabella was no longer there. He looked at his bike and found it was fixed and looked brand new. " Arabella" he whispered, knowing that she fixed his bike.

A/N: I know Miko tried to convince Jack in the show but I wanted Arabella to talk to him and give him quotes from Dumbledore.

The spell Confundo is a charm that causes the victim to become confused and disoriented.
