Jason works too much.
If the job is beating up bad guys and trying to trip up Bruce still wanting revenge. But he does it literally all day long, his knuckles hurt from punching people's faces all the time so now he just started using weapons. However, even Jason's weapons decided that they needed to take a day off and decided to break down.
So now he's taken a vacation. No, Jason didn't decide that, you literally dragged him into house and helped him treat and heal every last scratch. Now he sits there grumbling and wiping his knife with a rag, you spend almost all your time here not letting him leave normally, Jason has the strength to leave and not even look back but you are his friend he can't do that.
— "At least I should go to gym."
Jason said, sticking knife, shiny from polish, into wooden knife board.
