Y/N and Barty have been dating for a year now. You, him, Evan Rosier, Regulus Black, Dorcas Meadowes and Pandora Rosier are all chilling in one of your's dorms when Dorcas, ever the unfiltered one, ask who is the one that listens to the others commands. Barty thinks its him, so Y/N proves him wrong, without him realising.
