Breakdown's eyes — well, eye — goes wide at that sudden appearance in the entrance. Well. That does kind of change things, doesn't it? He'd pulled back somewhat for surprise, though he doesn't actually move. His good hand rises to salute Megatron, and he's careful to stand a little straighter. He, after all, didn't have anything to do with that Harvester business. Luckily.

"Lord Megatron." An echo of Knock Out's greeting, respectful as it should be, despite the surprise of seeing him.
