The Walking Dead: 50 Greatest Deaths So Far
22. Dawn

The Episode: Coda
Prone to slap-filled mood swings and frequently impossible to get a read on, the leader of the Grady Bunch pushed her arrogance too far during her trade-off with Ricks group in the fifth season. In return, Beth finally stood up to her, stabbing her with a pair of scissors in the process, only for Dawn to instinctively react by shooting Beth in the head.
Amidst the shock, a distraught Daryl returned the favor.
21. Dr. Jenner & Jacqui

The Episode: TS-19
In the first season finale, Dr. Edwin Jenner nearly caused the deaths of everyone in Ricks group by trapping them all within the CDC to give them a painless end.
Understandably hopeless and with nothing left to lose, Jenner managed to nonetheless be convinced by Rick and the group to give them a chance, allowing them to escape as the clock wound down. Jacqui stayed behind with him, the two survivors choosing their own fate, and helped end the season with an affecting bang.
