O'Connor gave a half grin, half grimace at the old nickname. He was sixteen and rather lankey when he got transferred from juvie to prison. (Guess a guy can't cause a riot, or three, without the guards looking to even the score.) American History X drek had been a legitimate concern for him, and half the reason he joined on with the Donnelly brothers was protection. He let it go though, Darko was one of the few people that O'Connor had no interest in fighting. Despite being a behemoth, even by troll standards, Darko had a subtle grace to his movements. This gave O'Connor the suspicion that he wouldn't be able to dance around him like most other foes. There was also the fact that one of the tamer rumors about Darko was that in a fight he had a tendency of "pulling a Mountain" as a few people put it. O'Connor generally wasn't one for gossip, but he put stocking in this since the troll could easily wrap even a single hand around a person's head.
O'Connor reciprocated the fist bump, his own fist comically small in comparison to Darko's. He motioned to his blank skin, "During my last bit of biz I got barbequed by this wacked out mage looking to purge the world of the impure. I'm hoping you can redo some of your old work and outdo the rest of it." He nodded towards Darko's current customer, "Looks like you're a bit busy at the moment though."
