Elsa looks up at the sound of the woman's voice and thinks there is a very high probability that she is looking at someone from the underground world. There's a moment of panic inside her, wondering if this woman is perhaps a vampire, and not a friendly one (they have a tendency to be pale like her). She grips her coffee, trying to direct any panic towards it so that she does not freeze the table and ground around her. Over her years of schooling she's learned to have much more control over her powers and it helps when she can direct her emotions into one thing instead of letting them fly everywhere.

"Uh.. no.. it's not..."

She hadn't been planning on staying, but it looks like she might be here for a little while now.
