Very good question! I actually think Riley redeemed herself big time. When the few left Fort Irwin, she stepped up her game, and in the war of it all when the waves of zombies were coming in, she really held her own, saved those two kids(should have stayed with her before the bomb), she saved puck, and just kept going stronger and stronger.

Also Kalani in a way. Getting to hear what he did any why, was slightly redeeming to know it was for the purpose of doing anything a father could do.
