Acetylene is the BD!verse AU in which Charles and Jason meet and fall in love. And if Erik weren't so jealous of Charles, maybe he'd be willing to meet the guy face-to-face. Wouldn't that be interesting...
Acetylene branches off from Unbound after Chapter 47, and contains a bunch of little Jason stories that are also part of the primary!verse; they're just grouped in the Acetylene series/collection because Jason's a major/POV character in Acetylene instead of a supporting character. :)
