I agree they can’t have her bitten and then compel Carol to shoot her in the head upon zombieification at her newly opened daycare. But I could see Abraham (in yet another heroic attempt to save someone) on the roof of a high-rise, holding her tenderly surrounded by a hoard of walkers and in a no hope situation, saying “I won’t leave you” and jumping. That would turn the screaming fits into tears IMO.
Or Carol taking Lori's place, from the comics. In the comic, Lori lives through the birth, but then dies in the siege of the prison, while protecting her baby daughter--they both die when a bullet goes through Lori anyway and hits the baby. That would SO work (a version of it anyway) in this show. The one I think should die is Daryl, again, for narrative reasons. I like the character and the actor, but his character's arc is over.
