It was an average day at Hogwarts, you are a Slytherin, you paid a 'visit' to Harry Potters dorm last night. When you walked into the great hall, you hear someone speaking at the Gryffindor table about a Slytherin tie being found in Harry's dorm. No one knows who it belongs to, it's yours and Harry knows that.

You snuck a glance over at the Gryffindor table and caught Harry already staring at you before he looked away, trying to tell Hermione & Ron that he doesn't know who the tie belongs to.
