Private to Aang.
There are a lot of people here who have...abilities that aren't bending. I've met a few, though I'm not sure if they can do the same things as Luke's father can do.
Who's Leslie? Another friend? Or Luke's sister?
I don't know the waterbender Katara all that well, despite us residing in the same place. I mostly work with Angel and Connor. I don't pretend to know what's going on in her head, but if she needs to do this, I'm not about to interfere. Me interfering with her doing things usually ends up with me soaked and beaten.
