Megatron waited a few steps out the door, not saying anything, because while he wasn't feeling any particular urge or desire to stay, it was clear (and curiously so) that Orion was.

"If you actually are having trouble leaving and need to me do something about that, tell me and I will simply haul you off," he said after several minutes, though he didn't immediately stomp over and, say, lift Orion up.

Not that that was such a bad idea, actually...
