*nodnod* Crossovers are tricky, a lot of the time! There's so much translation work to do before you can even start letting the characters get to know each other.
I'm thinking before the next round I might make a "helpful hints for making a character list that plays to your strengths" post, once I can organize my ideas on it a little better. There were definitely some characters on my own lists that I didn't know what to do with once they got any prompts.
