(OOM:
How do you dare to tell me that I'm my father's son
When that was just
an accident of birth?
Warning for the vaguest possible references to rape.)
Sam is at a table within range of the dart board, chucking darts at said board.
His heart's not entirely in it - you can tell because, while he's hitting the dart board every time, he's not hitting the bullseye every time. If anything, he's got a bit of a wistful thing going on.
But he needed to think, after that exceptionally odd night, and if he doesn't have to think about what he's doing, that comes a bit more easily.
