It's true, she didn't say she was new, but...a metalbender grifting people on the streets of Republic City without Lin Bei Fong hearing about it? Not likely. Not likely at all. So it's Bumi's guess that she's a refugee from outside the city dragged here kicking and screaming just like he was.

Which is odd seeing as he was here, just not now here.
But...whatever.

"Oh? So which of those two groups do I fall into?"
