A rather large fan of the I Know He Knows I Know game, what with his prior job and all, Edgeworth has no problem with returning the raised glass with a wave of his hand and a genuinely pleased smile. He's actually glad to see that Nigel and Alex are there, after all.

Of course, that may be due to the fact that he's been able to watch them at his leisure, but still, the end result is the same, isn't it? And that's what counts, in a game of body language.
