Birthdays, Sequels, and Timelines

Been giving this birthday party fic some more thought, and you know, I think I can make it all a part of the sequel to Practical Applications (which has long been titled Transformative Variations). Looking at the story now, a lot of how Tony behaves ties in perfectly with his action in the sequel. I think I just need to tighten up the timeline I'd initially anticipated.
