Turning toward her, Stiles notices the wind whip by, rustling both their hair and after a moment he shrugs off his jacket and drapes it over Lydia's shoulders, tugging it close and nodding to himself. He's got his layers, as per usual, so the afternoon chill doesn't bother him just yet.

His eyes track down to the pretty sapphire dangling from her wrist and nods. "Undine, then. Okay, that's not bad. It's a pretty city, definitely very... watery," he says, then continues. "They have a killer library though, in the Salt Spire. Anyone can visit but only people that are Undine are allowed access to other parts of it, apparently."

"Well, you don't have to live there if you don't want to," Stiles tells her. "You could live in the forest if you want. You don't have to be confined to the underwater city."
