X was less than gracious when she released him and that's still annoying him as he heads up the stairs. But by the time he's reached Fi's room, he's let it go (or at least put it away for a while). There are more important things to think of, like making up for three weeks of incarceration or incapacity. And washing that damn place off him.
He bangs on the door hard. She wasn't downstairs (he checked) so she must be up here.
