Adrienne pissed off to some tech noir dimension, and as far as I know Cordelia is bumming around on her trust fund still, maybe trying to plead her way into the hellfire club.
They also have an older brother who resides in a mental institution courtesy of her father, basically her Dad didn't like having a gay son.
The backstory of the Emma Frost limited series wasn't consistent with some issues of Gen X though which kind of pissed me off.
I don't get Emma and Cyclops either, I mean why would she want him at all, unless he likes a good paddling or something wierd like that.
Cyclops: Thank you Ma'm may I have another
