I'm not a big Carol fan but I'm a fan of characters who change through the course of the story. Saving everyone at Terminus has to get her a few brownie points at least.
Kind of hoping it's Abe as he's like a TV anchorman paired with women who are much too good looking to be paired with him. Sasha and Rosita can do better IMO. His romantic life is tedious.
The only couple I've actively shipped is Daryl and Beth. Glen and Maggie are OK but Richonne and Abe/Sasha bore me.
