I mean, a large part of that is that baby Cable also represents the family that she wants. That's why when she's with Franklin and baby Cable, she takes a moment to note that they make a perfect nuclear family. You can't say the panel makes no sense with context and then say you get she was overwrought when her being overwrought IS the context.
Franklin's return didn't make her regress, facing Ahab and being brutal against his Hounds and being rejected by Jean made her regress.
No, you're wrong about that. Days of Future Present was originally going to be a story that heavily featured Caliban and Senator Kelly, likely it would have featured his assassination in a manner similar to how it originally was to set up the idea that the Shadow King was going to bring about the Days of Future Past. I don't know what role Rachel and Franklin would have played in it but Liefeld was using it to prop up the planned Mutant Wars crossover. The Phoenix Limited Series was cancelled, although I think Claremont might adapt it in the next volume of X-Men Legends if that cover and his desires are anything to go by.I agree that DoFPresent is a pivotal moment for Rachel about confronting her past, it just seems out of place when the story arc happened, she progressed so far by that point with starting a new path. From what I understand, DoFPresent was adapted from a storyline that was supposed to be the Phoenix Limited Series. Having that story then, when she abandons the X-Men, goes to Mojoverse to reinvent herself then push towards the formation of Excalibur/Omniverse/Necrom/Merlin story...if DoFPresent was just a mojoverse production, over-the-top entertainment in between these event...it would have worked better for me.
We wouldn't have all those hilarious Jean being abusive to Rachel memes though.
Besides, the point is that in spite of how far she progressed in Excalibur, she never actually confronted Jean, got to face Ahab or came to terms with what happened to Franklin. Maybe who she had become in Excalibur at that time could handle one of those things, but all of them? To expect her to stand tall and confident in the face of it all would reduce her as a character by making her too perfect. What makes Rachel great is her characterization.
