At first James was slightly amused by Finn's obvious discomfort at being embraced - it brought back faint recollections of childhood, and the sheer confused panic that descended when a girl was crying and you were obviously supposed to do something about it. But though he'd been attempting to steer the subject away from the Longbottoms, how he and Diana might have known them and what they thought of their apparent deaths, having a flatmate injure himself was a bit more distraction than he'd been aiming for.
"Merlin!" he exclaimed, starting forward. "How bad is it? That thing's bloody hot ..."
It was a frightening moment: six months ago they could have just popped over to St Mungo's and had the whole thing cleared up in minutes, but that was out of the question, now. Dittany was good, but it just sped up the natural healing process - and despite Diana's confidence, James was fairly sure that a bad burn could cause serious long-term damage, particularly when it came to things like hands.
But he'd scarcely had time to consider all the possible consequences of that one little mishap when it registered that Finn, contrary to all expectations, scarcely seemed bothered at all.
