Arthur smiled and made nice with all the introductions. Even with Doom. It was obvious no one trusted that man and he didn't look all that thrilled to be there in the first place. He had to wonder if the reasoning behind his invitation was so that Reed could keep a closer eye on him. He raised an amused eyebrow at Reed's joke (it was one he had made himself in the company of friends, albeit an occasional annoyance when people actually believed that's all he did). Despite Reed's speech, Arthur was still skeptical as well.
"He has a point," Arthur said regarding T'challa, "I'm as leery of the man as you, but the election, as far as we know, was fair."
