Jessie is the most recent addition of all the characters in this list, but she really does deserve a chance to make it in Season 6. She's already proven she's a sweet character, and in a grim, bleak world, that goes a long way towards improving the mood without resorting to Tara and Eugene's level of buffoonish comic relief. Rick's having a progressively awful time, and if Jessie accepts that her abusive husband's death was necessary, there's no reason why she can't inject a huge amount of hope into Rick's life. They could be a great couple if she adapts to Rick's mentality, but unfortunately, TWD doesn't like showcasing optimism or joy, and that could mean bad news for Jessie. And Rick.
