Rachel fans are so used to no representation, we're always hopeful this new event or any inclusion will be the fix we experienced when Rachel was a POV character. But being a C-list character makes her so much cooler than the mainstream X-Men.
I was re-reading Uncanny 210, maybe the last time Rachel had the spotlight on the main stage. Rachel wasn't in it but it was interesting to read what her teammates/family thought about her while they were looking for her after she disappeared. Rogue - "Is she dead? It's cruel, but sometimes ah think that'd be for the best. The girl certainly has some serious problems." Kitty - "Rachel deserted us Peter...What do you do when people you trust, people you maybe even LOVE, betray you?" Piotr - "As Rachel herself told us in happier times, if we give up, then all our sacrifices...will have been for nothing" Ororo - "I don't object to your [Logan] attempting to trying to stop Rachel, but you shouldn't have done it alone..." So Rachel did the sacrifice again that aligned everyone into being a better team. Then that same team basically gave up the search and forgot about her. Ironically the same thing happens after Extermination (And Excalibur when everyone thought she should just die for Britanic). Rachel and Kate should definitely be the exes that remain being friends.
