For interacting specifically with Elsa
[If only she hadn't been on the main island.
She hasn't been, not properly, for weeks now - it's been one thing after another and her powers have been going off at random far too much for her to dare risk being among people. And then she had to choose today to take the train over. It starts with the familiar, dreaded hum of magic in her fingers - no matter how she rubs her hands it doesn't go away. Well-- going outside so soon was a bad idea, obviously. She's not rewady yet. She'll just have to hurry back to the museum island before she runs into anyone, and--
The gloves don't help. There's frost on the tree trunk she just touched with her gloved hand. Elsa stares in horror as it slowly spreads over the bark, before she turns around and continues walking - not towards the trains; she can't, anywhere else - with renewed urgency in her steps. It's not the easiest thing to see considering the snow already on the ground, but now, with every step she takes ice blossoms under her feet, spreading around her.
Should anyone spot her now, they'll see her half-running in the rough direction of the forest, cradling her hands to her chest, and... this being a loss of inhibitions, that is unmistakingly tears running down her cheeks.]
