Het for Hermione? Long-term preferred, but I'm happy to try it out short-term to see how the dynamic works.
A fun Christmas at Grimmauld Place. Something involving the Yule Ball or a Christmas party. Tensions running high in the common room/study session. A time-turner mishap leaves her stuck with the Marauders. Sirius returns from the veil and Hermione spends the summer there. Horcrux hunting. Hurt/comfort-ish for Draco. Any fix-it lines, canon divergent, character lives, or post-war lines.
would anyone be interested in a Supernatural (the show) game? Something AU, slice of life etc. I'd love more than just the brothers or destial, but have people bring in Charlie, Adam, Jo, Jack, Claire, etc etc. Make it a fun group thing!
