There was some sort of magic the physics that allowed the profoundly hung over to move with such speed, enabling to reach the toilet before the inevitable. It wasn't fail-proof magic, but more often than not it worked out for the best. For a moment he considered poking about for one of Lily's hangover cure potions, but the trouble with them was they just tasted so utterly vile. That always seemed a bit counter-productive to James, if the cure made you want to gag as much as the affliction. Regardless, he summoned a vial from the kitchen, letting it set down on the table next to the sofa. Nothing left to do now but wait. In a round about way, at least he'd have some early morning company - assuming Sirius ever managed to drag himself back downstairs.
In the meanwhile, James had also scrounged up a bag of crisps. Sprawled out on the sofa, flicking through channels did little to keep him actually amused. When Sirius finally did reappear, he looked far more like the zombies James liked to say they were. Eyes flicking away from the bright flashing lights of the very pretty television, he pulled his extended leg closer to his body to allow Sirius room to sit down.
"I miss a party?" he smirked before taking the licking the salt from his thumb.
