Told her to stay away? Elsa jumped a bit at the sudden snap, little snowflakes dancing through the air - but she cleared them quickly with a flick of her fingers; she had merely been startled, that was all. No big deal. Apparently her roommate was on edge and she couldn't blame him - he'd just tried to run out the door and then, not realizing that ladders were a thing for those who preferred not to parkour, had hit the floor kind of painfully. Or she assumed it was painful, anyway.
"Marc, hi," she gave a small wave in return, a wiggle of those slender (cartoon? Woe) fingers. "I'm Elsa. This place is...really something else. It takes some time to get used to it, but even then - it still manages to surprise most of us."
She'd been here for many, many weeks - constituting months, even. Elsa had lost track of time since it passed so oddly in their corner of the universe, moving forward and then getting yanked back.
