Generally speaking, she's a shut-in. She'll wander around and look about sure, but she rarely really talks to people and her list of friends can be counted on one hand, likely with one finger. She's probably told noone about her living arrangement unless she's had to for a class assignment or something, and Sam likely knows her setup if he's actually taking care of her, since that's where she lives, but I assume it to be a mystery to any who haven't managed to sneak in or work on staff.
After all, she's not ALWAYS in her room ^^
