I just had a horrible thought.
What if CC2 makes a Sola sequel, and its set something like ten years after Sola, and you meet the Sola cast in it half way through. Only when you meet Red, he's a senile old man in a wheel chair. The reason being that he was never built to last, so once Baion's plan was done, he started to to wither away because of his accelerated aging. And you get to see the look of despair in Elh's eyes from the knowledge that despite giving up her immortality to be with him, she's still going to outlive him by decades. Alongside the utter tiredness of Chocolat, who's had to give up her dreams of finding a man and settling down because she has to do all the hunter work now to support them.
I don't want this to happen, but it really sounds like something current CC2 would do if given the chance.
