After his
conversation with Utena Robin felt distinctly in need of a drink. Well, several drinks. As many as possible. And, perhaps, a nice soak in the sauna.
So, making his way back to Ravenclaw, the Puck focused only on the glorious bar that awaited him. He was not in the best mood, angry with himself and worried. So, perhaps, it was understandable that after giving the password, Robin neglected to shut the door to the Ravenclaw common room.
Going to the bar, Robin grabbed a bottle of rum and poured himself a glass. Normally the Puck hated drinking alone; but, he figured in a place like this, he was bound to have company sooner or later.
