This is being written in between 'Out of the Past' and... whatever episode follows 'Out of the Past,' I don't remember the title. So it will obviously be overtaken by events and doesn't fit into continuity and you know what, I don't care, because get it, Lin.
Metalbending lessons and total smut.
(ETA: I thought I'd finish this story because it wouldn't fit in with continuity, but then I decided to fudge it as an AU. It's going on and actually might develop a plot, though given my track record of starting stories I can't finish, I hope nobody gets too attached to that.)
