It was suppose to be a routine Decepticon signal- Bumblebee and his team follow the Decepticon signal, fight them, and take them into Autobot custody.

But with all the non-threatening and deranged Decepticons they'd fought, they'd forgotten that the Alchemor housed some of the most dangerous and most wanted Decepticons because of how dangerous they were.

The signal had come from an abandoned factory- one that was good for hiding it- and Bee had quickly split up his team to cover more ground.

He'd sent Sideswipe and Strongarm to the underground tunnels under the factory and ordered Grimlock and Drift and his two Minicons, Jetstorm and Slipstream, to scout the ground level, and he'd gone to look around the catwalks and higher levels.

None of them had noticed something watching them from the shadows.

"Fixit, do you have any information on our fugitive?" Bumblebee asked the Minicon back at the Scrapyard through the comms.

"Hm, let's see..." Fixit murmured from the other side of the commlink as he looked through the Alchemor's prisoner manifest, then he froze once the file came up. "...Oh. Bumblebee, you have to get you and your team out of there, NOW. It's not safe! You need to-" Then the comms cut out, replaced by static.

And it made Bumblebee realise he'd probably just made one of the worst mistakes in his life.
