As Orion's whole demeanour changed like dispersed gas, Megatron felt something twist around his spark chamber - an out-of-place, sudden surge of charge that scratched over the ciruitry there and then flickered out, gone.

When Orion had turned around, Megatron's expression was quite normal, even if his optics might be glowing at a slightly deeper colour still.

"If you hadn't reacted somehow I'd have been... concerned." And would have set about teaching the librarian to assert himself, regardless of anything else. No one should have to take being harrassed. "So no need to aplogise, you handled that rather spectacularly," said Megatron, lifting one hand off the hilt of the sword to wave the concern away.

Then, however, he looked down at Orion, look turning slightly arhced and inquiring.

"It seems to me, however, that you were the only target..?" It was sort of embarrassing to admit he hadn't actually heard precisely what the mech had said. He'd noticed his arrival in the back of his processor, but he hadn't pinged as a threat... not until Orion's presence had sort of exploded.

And most delightfully so, as well.
