A wary demeanor or response isn't anything new to Korrin. As a 'Qunari' and a mage, she gets plenty of suspicion just based on those two factors. It's not fun to be judged like that, of course, but if she made a scene every time that happened, she likely wouldn't have time for anything else.

Glancing down to the lock, she raises an eyebrow. "Looks new to me. But yeah, Araceli and I did the same for ours. Not that anyone would really have wanted our crappy room at first, but we had planned to fix it up, so things could have changed. She's better at it than I am, but I remember what goes where, more or less." If nothing else, she can hold things in place for Rey.
