The mirror Thor does not appear to have the slightest clue what the mirror Tony is going on about -- but he can obviously read from the tone of his voice that he's being insulted again.

Just as Tony yanks Thor back, the Mirror Thor slams against the mirror, enough so that the mirror vibrates visibly.

"You don't think they can break out, do you?" Thor asks as he jogs alongside Tony; the hall of mirrors is a veritable maze -- there doesn't appear to be any straight way out of it.
