'I won't be long. Promise I won't, and if you need me, use your card.'

He knows he should stay, that Random probably won't be alright on his own. But it'll be worse if he can't at least try to get Martin to change his mind.

'There's something I have to do. Try to sleep.'

He gets up quickly, before he can change his mind. He doesn't like leaving Random like this, so he turns away to pull some more clothes on. He'll be as quick as he can.
