Carol got them skills from Rick during the time jump after they got run off the farm. She was still crying over Sophia and only thinking about trying to get a sympathy fukk from Daryl when Shane was alive.Boy it sure is a good thing that terrible guy Shane taught Assassins Creed Carol how to be a goon or the show would've ended at terminus
Being alive in the comic doesn't make you safe on the show though.I don't think so, he is alive in the comic. He never really came around there. You do realize that he is a coward that ate good while his congregation starved and were killed outside his door during the majority of the time the world went crazy. The only person who could forgive him is Morgan because he is insane.
