[ She takes a sip of her soda. And says nothing for a long moment. Then she takes another sip. And starts to talk dully. ]

You know, there is no soda in my world. It was one of the first things Sokka showed me in Luceti. He and Toph and Zuko were all there before I was, and then Toph went home... and then Zuko... and that happened, three or four times with Toph and Zuko and with so many other people... but Sokka was always there... until he wasn't. About two months before I showed up here. And then he was here. [ And she's crying quietly. ] But he'd spent so much more time at home. And he didn't know anything about Luceti. And that hurt, but it was still Sokka, you know? So it didn't really matter.
