Thanks. I don't have a lot of fixed headcanon because I like having different interpretations to play around with, except that everyone is much more competent than on the show. But I never had a problem coming up with AUs (at least not for SGA, so many possibilities!), and I love worldbuilding. Plot and character voices and sitting down to actually write it are much more difficult! I like the image of Teyla teaching Jennifer magic, so maybe I can write a bit about that.
