It's doing damage, in the sort of inscrutable way where Logan can't really tellhow except that he can smell fresh blood, somehow. He's punched in the face and almost lands on his ass, but manages not to. Manages to stay on his feet. He shakes his head to clear it, which doesn't work, but he still hears Argo's words. Snorting once, Logan takes a moment to rebalance himself while he says;

"Funny, thinking the same about you. My money's on me."

The instinct to run has never been strong. It's why, for all that the animal motif gets bantered around a lot, Logan doesn't make a good one. Pain and the 'or flight' response are things shoved aside and, for as long as he can retain some motor function--

He attacks again, efficient in driving in on that one angle that does not favour Argo's better arm, claws hunting for an opening. No amount of disorientation can negate the worth of his impact and momentum.
