The curly haired guy said “You left them behind, we both did” then he ran away and left him with Glen and he tells Glen “They didn’t panic, we did”. I’m not sure what he meant, maybe I missed something from the past episodes, and then the walkers come and tear his guts out and he screams. But wow, that had to be the most gruesome death out of the whole series.
In a previous episode, Aiden and Nicholas were training Glenn, Tara, and Noah to go on supply runs with them. During the training, Aiden said that they lost some other residents of Alexandria while on a supply run. Aiden said that it was because they didn’t follow his plan (implying that they panicked, and that’s why they didn’t make it).
In last night’s episode, Nicholas and Aiden seemed to suggest that they were the ones who panicked and they sacrificed the others on the team in order to save themselves on the previous supply run.
Death bed confession. He knew he was done for and told Glen the truth that he and his gutless partner would run for the hills and leave everyone behind.
Probably explains why they would tie up a walker in a tree. Get the newbs to think they were bad asses by poking a stick at a live walker, lead them into some dark building to scavenge, collect the stuff, newbs get wasted, they get home with the goods, and everyone including mommy thinks their the BMOC.
