Severus scoffed quietly, clearly not prepared to be impressed by anything the boy had to say. He had no patience for levity. It didn't exactly inspire confidence, but there wasn't a damned thing he could do about it now - Potter was right about that much. So he only stared, cocked his head sharply in what just might have been a gesture of assent, and turned on his heel to march back into the dark of the forest, to find a more sheltered place to Apparate.
At least it would all be over soon, one way or another. He thought he might not mind leaving it all behind, the way Potter would be doing in a matter of days. He'd lived for this for too long, and now it was ending the wrong way entirely, and there seemed to be very little point left. To anything.
