There's probably never going to be a point where Orion can enter a room without scaring Starscream momentarily senseless. Once he recovers from the initial jolt of fear though, he turns to him, scowling at nothing in particular. He was just in that bad of a mood that everything deserved his ire at once.

"These? A couple of life forms I came by not too long ago... from what I understand they are unusual on this planet; not native, or at the very least never seen before...." He growls and raps on the cage once more before looking at Orion again. "Can I help you with anything or are you just generally poking about."
