"Arya?" Sansa's sister, right. Luna hasn't met her yet but it makes sense to imagine that she would be drawn here like her sister was, and maybe deeper inside Arya's twirling in joy at the sight of home again. And with how Sansa's been looking for her sister since the Arena began, of course Arya's the first thing on her mind. Luna would be looking for Phi too, if they were in a replica of the Rhizome. Or maybe Kyle would be a better example if he were here (thank goodness he's not) since Rhizome 9 was his home, not Phi's. Either way home has a certain draw regardless of how she feels about it, and she doubts it's much different for Sansa and Arya.

There isn't much question about that, then. "Right. Do you know where we might be able to find her here?" Luna does trust Sansa to know her sister, but it is a big place and two people can only cover so much ground. It's times like these that she misses the added perspective of hidden cameras.
