It takes a moment for her to realize there's someone talking to her before Philomena turns her middle-distance-then-startled look to a practiced smile and wow this other girl is actually some sort of fairy, which only makes her smile widen.

"Oh! Thanks. I love yours; pink is by far my favorite color." ...not that anyone could tell.

There's a fidgety moment of what-do when meeting new people in a magical city, before she finally settles on something like an introduction. "I'm Philomena. I just got brought here." And hopefully that manages to explain the disorientation.
