15. Walk With Me
Walk with Me has an ending that should still send shivers down your spine, revealing the full extent of The Governor's twisted psyche whilst cementing him as an effective threat for Rick and the gang. The build-up to its plot twist, though, leaves much to be desired.
Though it manages to effectively reintegrate Merle into the show after a two-season absence, the episode spends its entire run away from the prison focussed on Andrea and Michonne's introduction to Woodbury.
Moving at a snail-like pace and struggling to find anything compelling to do other than share insight into Michonne's suspicious nature, Walk with Me ruins the momentum of the season only three episodes in, and watches like nothing more than a cheap set-up for bigger and better things.
