Siddiq continued to struggle with the effects of PTSD and what they meant for his future.
He spiraled out of control when he realized that someone was killing people in Alexandria. He went to ask more about what was going on with the walker.
However, they had to entertain a whisperer who died from the get-go thanks to Siddiq.
Siddiq then tried to commit suicide, but Rosita saved him. In the end, though, it was revealed that Dante is a Whisperer and that he alone would kill Siddiq. He did.
Carol learned that Alpha told everyone she killed Lydia, prompting Carol to lie to Lydia and say they were going on a mission.
But Lydia realized that when Gamma knew she was alive what Carol was doing. Lydia told Carol she was done with her, struck her with her stick and went off on her way.
Gamma retreated to a bush crying about the whole thing because she almost murdered Aaron in cold blood.
