Sunday's episode of The Walking Dead reveals that someone is ambushing Saviors and potentially killing them. The episode's ending offers a subtle clue to the killer's identity when a member of the Saviors is suddenly attacked by someone he knows.
During The Walking Dead seasons 7 and 8, the Saviors were the hated enemies of Alexandria, the Hilltop, and the Kingdom. Led by Negan (Jeffrey Dean Morgan), the Saviors oppressed, antagonized, and took advantage of the three communities until they finally banded together and decided to fight back. At the end of The Walking Dead season 8, the All-Out War came to an end with Negan's defeat at the hands of Rick (Andrew Lincoln). Now without a leader, the Saviors have been given a second chance by Rick, who is actively working to get his former enemies back on their feet.
In this week's episode of The Walking Dead, "The Bridge", a member of the Saviors, Justin (Zach McGowan), stirs up trouble and causes an accident that leaves Aaron (Ross Marquand) without an arm. After getting into a fight with Daryl (Norman Reedus), Justin is kicked out of the Saviors by Rick and forced to leave. During the night, Justin comes across someone he seems to know before being abruptly attacked. Over the course of the episode, several references are made to Saviors who have mysteriously disappeared, which suggests that Justin is the latest Savior to meet an unfortunate end. Since he was told to leave anyway, it's possible that his disappearance will never be discovered.
Justin's reaction indicates that the killer is not only an established character on The Walking Dead, but someone that he may actually trust. This means the killer isn't Daryl, or anyone else who has an obvious hatred of the Saviors. This reveal could point the finger at one of their former high-ranking members, Eugene (Josh McDermitt), or even Alden (Callan McAuliffe), who at least appears to be sympathetic towards them. Other options include Dwight (Austin Amelio), who hasn't been since he was exiled in The Walking Dead season 8 finale, Oceanside and the Whisperers.
The recent killings come at a time where relations between the Saviors and the other communities are improving but remain strained. Not everyone in Alexandria has forgiven the Saviors for everything that's happened. Many, like Daryl and Rosita (Christian Serratos), work with the Saviors regardless of their personal feelings. Meanwhile, Rick wants to help the Saviors rebuild, and is only beginning to realize that not all of his people are on board with this decision. One of them could be responsible for the disappearances, or it could be someone within the Saviors who's striking out at them for working with Rick. One thing is for certain: betrayal isn't far off in The Walking Dead season 9.
