In hindsight he should have expected for the blow to not do anything, but at the same time it's a useful weapon to have at his advantage even if it wouldn't do any real damage. That had... been somewhat the point as he wasn't out to kill him, of course not, but it could make a useful defense weapon, too. As is evidenced by him using it to block the kick and a few of the blows, not seeming too bothered by the ones that do hit. It'd take more than that to really bother him.

The problem is him hitting the wall and he's hissing to himself with that all too familiar sound of rattling while he drops the mop and attempts to reach out to grab for Blitzø's neck with his hands to maybe get him to stop and dig claws into skin. His tail moves to grab for one of his wrists, hoping to use the momentum of the movement to get the hit to miss or, maybe, dislocate if he was lucky.
