"Hello." Arthur sounds a bit flat in affect, but it's nothing personal, he just talks that way. That he's giving his teammate a Look while addressing the group at large is purely coincidence, surely. Why must you encourage this mouthy guy, Eames. Why. Oh wait, it's because you're a giant pain in the ass.

Without actually smiling, he manages next to express a moment of neighbourly acceptance of what he hopes is not the beginning of a trend of making fun of him for what he likes to think of as no reason. "All right... if everyone wouldn't mind showing off their Delta transmissions, we can get this show on the road." He's not exempting himself from this request, at least; his CiD's already out.
