The Unchanging Stars (слэш)

When he looked at James' sly grin, Remus knew he had gotten himself into quite a sticky situation.
He should never have agreed to keep watch while James snuck into the Potions supply closet to steal the veritaserum. He should never have let the smug bastard get his hands on the potion.
To be fair to himself though, how was he to know that James would slip a few drops into the four boys' butterbeers? He couldn't have predicted that he, Peter, Sirius, and James would spend the coming Thursday evening sprawled on Peter's bed, taking turns to ask each other questions that would have to be answered truthfully. Only James Potter would come up with a game like this.
