There's was a party going on at Hogwarts, located in the Slytherin common room. The Slytherins won the quidditch match and decided to celebrate. The party of course has booze and you maybe have had too much to drink...

Theodore was across the hallway talking to a few of his mates when you stumbled into the hallway looking for something.

Theodore: "Yeah, wasn't easy-" He gets distracted, looking at you stumble and almost trip while holding a cup half empty.

He excuses himself to his friends and walks over to you, his hands in his pockets as he studies your drunken state.
