Draco Malfoy came in and was Not Amused. He went through both Neville's and Seamus's things like it was nobody's business and did not give two craps if he destroyed anything valuable along the way. He was VERY OBVIOUSLY LOOKING for signs of Dumbledore's Army things and would tell Longbottom to shut the hell up if he protested.
Neville & Seamus (but mostly Neville), is there anything in particular you're cool with Draco breaking and/or confiscating? Let me know!
