The Walking Dead: 50 Greatest Deaths So Far
30. Shelly

The Episode: JSS
Carol warned her that smoking would kill her. While watching Shelly having a smoke outside within the safe walls of Alexandria, Carol - and viewers - were taken by complete surprise when a Wolf came from out of nowhere and slashed her stomach.
Though we hardly got to know Shelly, her death was a shocking moment that immediately jumpstarted the episode and raised the stakes, demonstrating how indiscriminately murderous the Wolves were in wonderfully chilling fashion.
29. Dave & Tony

The Episode: Nebraska
Dave and Tony wandered onto the scene in season two, coming across Hershel, Glenn, and Rick in the bar where the latter duo had found Hershel drowning his sorrows in the wake of the barn incident.
In a wonderful sequence, the tension underlining the groups conversation continued to escalate until the two men drew on Rick, who managed to beat them to the punch and finish them both off.
