The comment about healing and recovering fast doesn't go unnoticed. Normally all of that wouldn't be enough for her to question it further (Claude's Crest for example allowed him the ability to heal himself without expending the additional energy that a healing spell would otherwise take), but then, even in her exhaustion, she notes Lenore's features.

Her eyes widen and then her mouth drops open in a silent, "Oh" of realization. There's no fear there though, having already spent enough time in Nocwich. She gives Lenore a weary smile in an attempt not to worry her. "Nothing a quick healing spell and some rest at the spa can't fix. I don't think I ever want to see snow again for a while yet."
