In my Marvel RPG game, Carol Danvers and Jessica Drew have a prior history together... basically they were FWB while they were Avengers together (in my game, Jessica recovered from her power loss and joined the Avengers instead of retiring, and remained with the team longterm).
In the same setting, I have Jessica and Tigra as exes.
Currently, Jessica is married to a woman, as well. It's a pretty femmeslashy game, and that's how I like it. :D
