In The Closet

“It’s them!” he hissed, and before either of them could think James had shoved the trunk back under Sirius’ bed, grabbed Peter by the shirt and dragged him toward an empty closet in the room. They managed to hide just before the door to the dormitory opened.

“We don’t have to hide!” Peter whispered furiously at him. “This is our room too!”

James mentally facepalmed. “Well, it’s too late to emerge now! How are we going to explain this? I just hope I didn’t leave anything on the floor.”

(Or, James notices that Sirius is keeping something from him and decides to find out what it is.)
