Same. Feel just as bad, if not more, for Katara too, who has had to deal with the MC's time traveling mind jumping bullshit twice, and somehow knows the MC's fate before we do, to the point where she willingly lets him go after getting pregnant with his child, and then the MC just drops off the face of the earth for decades in her mind. I honestly don't know what possible way MITY is going to resolve the ending that doesn't leave me feeling empty.
Edit: Although this conversation did give me some hope for a happy ending as opposed to a bittersweet one
I do gotta ask though, have they confirmed they're not going to come back to this series ever again? I know they've pretty much covered all the main characters and time periods in the animated series, but there's a whole universe of other Avatar content out there that they could possibly cover as halloween specials or something similar, provided there's other chicks in the expanded universe, because I haven't actually explored any of them completely. Plus with the establishment of Avatar Studios it doesn't seem like Nickelodeon's going to stop pumping out Avatar related content anytime soon, just seems like a waste for MITY to let a franchise with so much future milking potential go to waste. Like after whatever their next project or two is, if enough new content has been pumped out by Nickelodeon I 100% think they should jump on parodying that.
— Albeit a bittersweet ending would be more suitable for this story, imho.
