He wasn't confused by a man dressed up like an Ottoman sultan, and didn't even let him finish his first word of his monologue before braining him.
If he knows he's in a fight (Which he does, according to what was just said), he's going to go for the win ASAP.
He probably just thought the guy was a nutjob (which he was probably right) and didn't bother with the monologue.
