^You should probably tag your comment as a spoiler. Also as far as I'm concerned that doesn't matter, especially as it wasn't her choice. Falin is Falin, the dragon is the dragon. The dragon doesn't have anything to do with her, as in the human woman, having "shy, nice girl with a whole lot of kinky hidden under the surface" energy as Bugpope is saying. Falin is explicitly herself, and her soul is separate from the dragon's soul. Plus spoilers for the end, Falin is back to being a human woman at the end of the series, with the exception of having feathers on some of her body now.
