Earlier in the day, you secretly slid a piece of paper onto Regulus' desk which you had written: Skip potions class? You watched Regulus read it and you could tell he was hesitant, given his perfect attendance and good grades, but even so, he mouthed a "yeah."
In Potions class, well, during the time of Potions class, you and Regulus were in the library. Obviously, the seventh years weren't supposed to be here during this time, so you both attempted to fit into the mixture of fourth and fifth years who were either studying or perhaps, finding books for a class project of some sort.
You and Regulus eventually found an alright place to sit down which was in the corner of the library, sitting beside one another, with your backs against one of the many bookshelves.
Regulus turns his face toward yours, his curls moving ever so slightly, and asks, "So, what'd you want to see me for?"
