I would have left her used by Chris and regretting what happened but it be too late to fix and John Ross had found Pamela - and a love triangle is created. Elena loves John Ross and John Ross loves Elena but he's not in love with her he's in love with Pamela who loves him. Elena could have been Alexis - always trying to get her man back. But I'd have left her with Christopher always breaking her heart. Again good set up - bad follow through.
Rereading this post I'll add:
John Ross like Scarlet, the protagonist.
Elena his Ashley, never really in love with him, but caring for him and what could have been.
Pamela his Rhett, the one he really loves, the one everyone knows he loves, everyone but Pamela.
Could have been fun.
