For many long-time viewers, Season 15 of "NCIS" brought a number of unwelcome surprises. Clearly, one of the less-than-pleasing plot developments on the show was the sudden departure of Pauley Perrette's forensics specialist Abby Sciuto. And while fans certainly noticed her exit from the series — and not in a good way — another event seemed to have many viewers even more upset: the brutal slaying of former MI6 agent Clayton Reeves (Duane Henry).

Killed attempting to protect Abby in the "Two Steps Back" episode of the show's fifteenth season, Reeves was a beloved character, and his unexpected demise had fans reacting quickly and bitterly on a Reddit thread devoted to the episode. Redditor u/Tiphini seemed simply baffled, writing, "I don't understand why they would kill off Reeves," then went on to complain that the episode also saw Perrette's Abby Sciuto leaving the show: "I hate that we are losing both Abby and Reeves at once." Redditor u/starsbetweenmytoes also vented their frustration at Reeves being written out of the series, saying, "I'm really upset about this. He was a great character..." And user u/trumpstinyhandssayhi summed up the general fan response, writing succinctly, "What the actual f***...why did they kill off Reeves?"

The sad truth is, the heroic-but-unwelcome death of Clayton Reeves in Episode 22 apparently made this particular storyline the most disliked in all of "NCIS" Season 15.
