Ever since the living Walkers became more dangerous than the Walking Dead there has been a running theme that if you don't kill all those who have attacked you they come back to haunt/kill you. Examples: Rick didn't go after the prisoner that escaped - He came back and let Walkers into the prison again. The Governor - Michonne was right to keep looking for him after Woodbury burned. He came back and destroyed the prison. Terminus Rick wanted to end them but Glenn and the rest talked him out of it. Later, Bob was amputated and the Termites attacked the church, this time Rick learned his lesson and was waiting. Daryl should have killed Dwight who later kills Denise. Morgan and the Wolves Maggie learns and makes sure everyone who kidnapped her and Carol were killed. I'm sure that there are a lot more cases but all of this is to say that on their first meeting Deanna recounts Alexandria's history making sure to tell Rick about the three who left. S5.E12 Deanna: For a long time, there's hardly been anyone here, living or dead, but still... we have lost people. And... I've done things. Rick: What have you done? Deanna: I exiled three men who didn't work out. And we both know that's as good as killing them. S5.E11 Michonne: Why don't you have any pictures of your people? Aaron: Oh, I took a picture of the whole group, but I didn't get the exposure right. When I tried to develop it later, it just... Michonne: Did you ask him the questions? Rick: No. Michonne: How many walkers have you killed? Aaron: I'm sorry, what? Michonne: How many? Aaron: I don't know. A lot. Michonne: How many people? Aaron: Two. Michonne Why? Aaron: Because they tried to kill me. S5.E16 Aaron: If we see them, we hang back, set up the mike, watch and listen. Daryl: For how long? Aaron: Until we know. We have to know. Daryl: You've sent people away? Aaron: Yeah. Daryl: What happened? Aaron: It was early on. It was three people. Two men and a woman. Davidson was their leader. Smart as hell, strong. I thought they'd work out. They didn't. I brought them in and I had to see them out. So me, Aiden, and Nicholas, we drove them out far... gave them a day's worth of food and water and left them. Daryl: They just went? Aaron: We had their guns. We had all the guns. I can't make that kind of mistake again. While writing this I just realised that Rick as Carol said when first entering ASZ "You're right even though you were wrong". I'm beginning to believe that like Hilltop not all was what it seems to be in ASZ. Hilltop conveniently forgot to tell Rick and Co about Negan recent visit. Which begs the question why was Deanna so desperate to get in reinforcements at this moment. In my post above about Deanna's videos we see that she sees a lot more than what she says. Before all hell brooke loose, Deanna became convinced that Nicolas is a liar and will do anything not only to save himself but also to attain power. PREDICTIONS: No! the exile(s) didn't just leave... they ALWAYS come back. Nicolas has hidden something in the pool table that Rick and Co need to find. (His son mentioned that Nicolas is overly protective of their pool table.) Someone from the outside told Nicolas where to find Rick's gun. Aaron is lying about the photo he has the photo but doesn't want Rick and Co to see who they had living there before. Just like the run with Aiden and Nicolas went wrong and they got their crew killed... I think the run to exile Davidson and his two companions went also wrong (Aiden and Nicolas aren't the most courageous) and Aaron had to kill two of them. Perhaps Nicolas had made deal with them but hadn't planned on Aaron killing two of them. (If this group had the same intelligence and experience as Rick and TF then just like Rick their first thought was to take control of ASZ - 2 men and a woman Rick, Daryl and Carol) If this Davidson is still on the outside looking in he knows he can not just waltz back in and therefore needs allies inside ::cough::Spencer::cough:: Enid may not be involved in the plot but she definitely knows about it. So Rick needs to get ahold of Deanna's laptop, Aaron's photo and whatever Nicolas has hidden in the pool table.
