I'd rather Helena die than Alison. But I'd rather lose Cosima. She's already hanging on by a thread in my mind. I love her but you can't make her sick in season one and still hanging on after season three. But I mean like, killing off Sarah or something, I wouldn't expect it and I doubt a lot of people are. I forgot how it even happened or why. But I didn't care because she died at the end of the series anyway. I think the purpose of her coming back was to end up teaching Yusuke and the others with psychic talents. Her coming back doesn't strike me like a DBZ thing though. She's old, she doesn't have a long time left either way, without her spirit orb, she's even weaker as opposed to Goku coming back even stronger because he trained while being 'dead.' I still think if we did a Kurama x Botan one, it could be pre-series or post-series since by then, Yusuke isn't really around much. But with just Kurama and Botan, it would be a little hard to find plots that aren't canon, even if Kurama was made a detective.
