Go to the scene right after the graduation party, where Scotty is peeing in his shower. He zips up his pants, walks through the bathroom door, and straight to his computer, where he proceeds to read an e-mail from Mieke.

In the next scene that takes place in Scotty's room, Scotty is at his computer, Cooper walks into his room from a hallway, and walks through the bedroom door, straight to the computer where Scott is. The doorway that had lead to Scotty's bathroom is now the doorway that leads to the hallway.
