I was just kind of going with the flow of your character... yeah, someone would probably come in and tell her to get out or after half an hour, she'd probably have her fill and wander back to her room. So either way, that sounds like a good idea - have them run into each other in the hallway or something. Any timeskips you want to do would be fine with me for the most part. :)
Edit: Actually, I can edit my last post to include Eva going back to her room, if you want?
