That makes perfect sense, and it didn't occur to me either for that very specific reason; and a good one at that, as Nick would never allow even a hint at such a topic-point. However, artwork does tell a story unto it's own and that does make absolute perfect sense (it helps I literally just finished re-watching the series before reading this) that she contemplated not living a life of normalcy, being the blood of the Avatar. It was beautiful and I'm really glad I read that, it packs a punch, emotionally. I really loved the style and story of the series, but like many others, had a problem with the development of the characters and the neck-break pace of the show towards the middle-end of the season. However, given that they've greenlit another 'book', I'm very excited to see where this goes. Hopefully it won't feel as rushed or sprint towards the end because this first season definitely felt like it was meant to be it, albeit unfinished and kind of a 'well, we'll see where this goes', but it pretty much wrapped everything up. 'Spirits', the second book, should be exciting, as she's clearly got issues there.
