8. Beth Greene
One the characters in the Walking Dead with so little personality that you forget she is in the show until she suddenly pops up in a scene. Sister to Maggie Greene, she is the sibling that should have been killed off when the zombies invaded her farm. Unnecessary is probably the best word to describe her, she might be nice but other than that, she has very little to offer. Apart from instigating the occasional sing-along, her main job is to hover around the prison and walk from cell to cell. There was a slight hint that she might have a crush on Rick, she gave him a very tender kiss on the cheek after he rescued Maggie, but that never went anywhere. They might carry that storyline on in Season 4 (they have to give her something) but unless Beth is a simmering psychopath behind that calm exterior; she is prime candidate to being killed off soon.
