Reminds me of Arnie Shankman from Anger Management.
Or Janice Soprano when she becomes all "humble"
Conor has not changed, and this is not the "old" Conor. Conor has NEVER been humble, he's always been cocky trash talker.
All of this is him pretending he's humble, he is trying to convince himself too, but once he gets a little nudge, he'll go back to his old self.
