Something something Danny being averse to fighting because he was forced into being a vigilante and fighting reminds him of those times when he was forced to fight. Dan who once held the same view but then his family died, he was taken in by Vlad, and fighting was still a necessity but now it also became a saving grace. He couldn’t afford to be vulnerable with Vlad’s suffocating presence controlling every part of his life so he channeled his hurt into anger and then that into fighting with Vlad. Fighting slowly became a comfort, almost instinctual, something familiar that helped him feel like he had control when he had none.
