Harry doesn't even know what to do. For a horrified moment, he just stands where he is, gaping like a fish out of water, his eyes somewhat wild behind the thick frames he's worn his entire life, gaze shifting in disbelief from James to Scorpius and back again. His lips move, but no words come out. He is, quite literally, shocked stupid.

Scorpius, for his part, is up and on his feet in seconds, smoothing his clothes and muttering something about fatigue. He's so quick that he forgets how weird it must look when he uses the front door to leave and locks up after himself. And, Merlin, he left his ruined shirt on James's bed.

Blinking in a daze, Harry turns to the door, watching Scorpius go, and then back to his son, brows lifted. "...He's still in school," he says, the first and only thing that comes to mind.
