This was originally going to go into Works No Longer In Progress, but it was really long and I figured if I cut a few things, I could turn it into an actual story. It's a sequel to Extremely Hot And Currently Female, in which Tony fell in love with Loki and met his own time-travelling son.
As a character, T.S. Lokason is ridiculously fun to write.
