Would she have been better off remembering that day? How would it effect her future...better or worse?
Remembering would be a constant reminder that Angel turned his back on her again.
Better or worse? Better I suppose. Then she would know that it wouldn't work with him as a vampire or a human instead of always wondering.
its consequences would have led Buffy to either try to find a way to break the curse once and for all
Meaning a vamp with a soul and no little drawback of going evil when shagging?
Thing is, that was never her dream. Her dream was for him to be human. Her dream was a life with him and a white picket fence, children and to just be normal.
The problem does not go away with just one side changing i.e. shaggable vamp. There is still the slayer aspect.
In a very real sense, the shaggable vamp angle was explored with Spike, like it or not, to show that even this option would fail in the end.
What Spike was in reality; a vamp who loved her and didn't go evil (chip prevented it) and then even that part was removed.
The capper? Spike gets a soul, is still a vamp and it is still not enough. In fact, it is played up as what Angel would have been like if in the same situation.
Sure, you can argue the attempted rape angle, but frankly Angel has done far worse to her on mental scarring.
If you want to add in the imagery from season 8, you have Buffy with both vamps; i.e. the best of both worlds.
The positioning of them in her dream is also of note. Angel in front and Spike in the rear. I'll leave the innuendo as is.
Take that for what it's worth.
I guess I'm asking if the simple knowledge of that day would have had a ripple effect on everything else that followed.
Not on Angel's side really since he did remember, and thereby knew that was the last option.
The curse removal wasn't that important to him or he would have been investigating that option
long before these events (or after).
I know that reality of the situation doesn't sit well, but that is the way it is.
On Buffy's side? I don't see how really except that she might have truly moved on. Would that have been beneficial in her relationship with Spike? Dunno. Maybe.
If Angel's curse being lifted was that important to her, she would have been investigating that option
long before these events.
This was not some sort of catalyst, or epiphany regarding Angel's status on either side.
If anything, it would have been demoralizing for Buffy to know that her dream could never be as long as she was the slayer.
The case isn't "If only Angel were..." but "if Angel were... and if I were..."
