Optimus Prime, Bumblebee and Mirage were drifting and driving around the town to celebrate their completed missions (cuz they don't have anymore for now)

Bumblebee: "We should have a race!"

Optimus Prime: "Indeed."

Mirage: "Alright!"

After 2 hours of free riding with Optimus Prime, Mirage started to notice that Optimus was very quiet

Mirage: "Uhm, Optimus?"

Bumblebee: "He's been awfully quiet.."

They formed back into their Autobot form and looked around for OP, he wasn't there with them anymore..

Bumblebee: "Optimus Prime...?!"

Bumblebee was more worried than Mirage

Mirage looked around and saw a not on the floor

Mirage: "Ay, Bumble, look."

He picked up the note, it said: "Looking for your friend, huh? Well, let's just say your not gonna see him for another while yet.. -signed by Megatron "

Bumblebee started to panick

Mirage: "Who the hell is.. Meg-la-don...?"

Bumblebee: "I can't explain right now! But we've- I've gotta go!"

Bumblebee formed into his vehicle form and immediately started driving.

Meanwhile with Optimus and Megatron

Megatron: "I said I wanted the Allspark."

Optimus was injured, Megatron had been hurting him since he refused to give him Allspark

Optimus Prime: "N-no! Never!"

Megatron kicked him in the face

Megatron: "I hope your little friends saw that note.. I'd really like to meet that blue retard.."

Optimus Prime: "Mirage is not a-!"

Megatron grabbed his neck

Megatron: "I don't care what his name is, he looks pathetic..."

Megatron dropped him then threw him in a cage and locked him up, then walked away

As soon as Megatron left, Bumblebee drifted outside the cage

Optimus Prime: "Bumblebee, go... This place is too dangerous... Here, take Allspark..."

Optimus Prime threw it to him

Bumblebee: "Ok-"

Bumblebee suddenly got punched and dropped Allspark, Megatron caught it

Megatron: "Nice try..."

Little did he know, Mirage was gonna come soon
