I don’t think she would have “birthed” jasmine. I think jasmine WOULD be her. The beginnings of the season were still putting her as Jasmine. Which is why she came back with Amnesia, and she was awoken as Jasmine. I think the difference would have been that she wouldn’t have been pregnant. Instead she was going to battle Angel. I also think she would have been doing more work to dismantle the Angel Investigations crew. You’re right though, this would have all played out in a way that would have completely turned her character away from how we knew her to be. Maybe she would have began the apocalypse and season 5 would have originally shown the post-apocalypse, like the original plan for 6?The original season 4 plan is one of the biggest mysteries we'll never know and theres so many questions about it. If Cordelia did go evil as planned then what would be her motivation to do that? Also what would the end of that season look like if they had that supposed sword battle scene between Angel and Cordelia? Would Angel have really killed her? The fate of Cordelia after season 4 always seemed like they were moving toward shifting the show drastically especially with her character.
