Um, yeah, user Jacqueline Walker gave me this idea (eeeevil thoughts), and Ninecrow did her part (as usual) in helping me with this.

I don't own anyone. Hasbro doesn't own my OC.

"Detection of Cybertronian activity in Kiev!"

"Moscow too!"

"Berlin!"

"Tokyo!"

"London!"

"Delhi!"

"Vienna!"

Optimus sighed. "Prowl, divide us up. We need at least three per city, but that's all we can spare."

"A lone Decepticon is rarely much of a threat for the right pair of Autobots, so we'll do two per city. Prime, Elita... Ironhide, Chromia... Magnus, Blaster, Wheeljack, Em, Ratchet... Flareup, Jolt... Hound and Mirage. Come with me. Everyone else is dismissed."

"Optimus and Elita, you're bound for Kiev. Ironhide and Chromia, you're going to Moscow. Flareup and Jolt, you're going to Vienna. Magnus and Blaster... ah... London. Ah... Mirage and Hound, Delhi. Ratchet and Wheeljack, Berlin. Em, with me, we're headed to Tokyo."

"My sensors indicate that we're getting close," Prowl announced.

"His spark signature feels familiar," Em bond-spoke back. "But from where, I do not know."

A strange car whipped out in front of them, it looked like a mash-up of different muscle cars.

"That'll be him. Em, tail him, chase him out of the city."

"Yes, sir!" Ember sassed him back. She took off after the car.

Prowl caught up to them outside the city. Ember had transformed, her blades deployed and lit aflame as her optics glowed red. She and the other mech were fighting, almost evenly matched in hand-to-hand combat.

Prowl could feel Ember's thoughts as he neared them. She was hostile.

"Em, love, listen. I don't need to know what he did, but I do need you to let him live. We'll interrogate him further at Base, but I need to scan him for ID first."

Ember pinned the mech hard to the ground and held her blades to his throat.

Prowl scanned him, and noticed something. Usually, Ember's signature would offer extreme interference. But her interference was minimal. That was only the case for...

"Siblings..." he whispered. Full siblings offered even less interference then half-siblings, so if Ember and the mech didn't only share a mother, she'd be even less of a signal block. "Em, I know where you recognize him from!"

"Where?" Ember shot back irritably. "Are you suggesting that I kept less-than-respectable company on Cybertron?"

"You did, but my point is... It's Lockdown!"

Ember looked down at the mech. Prowl was right. It was her brother! She got off of him, her blades extinguishing and retracting. Her battle mask snapped open and her optics turned back to their calm, neutral violet.

Lockdown looked up at his sister. "... Emmi?" he choked, getting up.

The dark Autobot hugged her brother, nearly tackling him again.

"Emmi. It's you," Lockdown confirmed, hugging her back. He glanced up. "Prowl?"

"Yeah. Why didn't you identify yourself before?" Prowl grinned, bemused. "You'd've saved youself a beating."

"I didn't know either of you were still alive."
