DD gives his boss a funny look. The sort of funny look one gives his breakfast cereal, when instead of cereal coming from the box he gets unprocessed wheat.
He thinks to himself "Is he trying to say as little as he can, with as many words as he can?"
He takes his hand and physically wipes most of the expression from his face, leaving behind only a thin film of confusion.
"Uhh, well . . ." He realizes he has nothing to say to Robert, and simply stops trying to speak.
Hearing Mr. Oshiro comment about Robert.
"Ahh, yes. This man is my boss." It sounds like he wanted to say much more than that, but is obviously deferring to his boss for now.
