Did anyone else go into the room or try? Anyone in the wing who didn't belong?

[ And yes, Stiles, her name starts with an S and she's a suspect. Thank you. But as has already been determined, only, what, two of the suspects even admit to knowing Lydia? And Sharon isn't one of them. She has absolutely no motive. ]

And back to my earlier question, what else could the symbol have been? Like I was saying to Susan, it doesn't look like an S. Since you were in her room, did you see anything that might have been similar?
