It's not just the looks -- it's the demeanor that's a little too familiar, and Starscream looks momentarily taken aback before he grits his teeth. He's not really sure whether he should disclose exactly just how he got here, but it might be better than a lie. He has absolutely no idea where this ship has been, or even whose it is -- shaking off the disorientation from the accidental space bridge trip, he finally regains some of his composure. His mouth tugs into a frown, and this time as he stares at Megatron, it's more calculating than it is curious.

"That's impossible," he says shortly, but he's still scrutinizing the other mech's face carefully. He doesn't look exactly like Megatron, but the similarities are too uncanny to ignore. There has to be some explanation. "I know Megatron -- quite well, actually -- and you aren't him. I was just with him, in fact. This -- " He flings one arm at the hallway around them. "Was a mistake."

Obviously someone else's mistake, judging by his tone of voice.
