So 5-6 years later, I see this challenge (maybe again, I don't remember) and finally figured out which story to write a Whatever Happened To for - my "What Makes You Different" story. It takes place in Spring 2018, just before the Boys release Don't Go Breaking My Heart. I'm just not sure what to call it.
It's also begging to be expanded into a much longer story than the 1-3 chapters, so I'll just post this shorter piece now, and work on expanding it later, posting again maybe under a different title.
