I've rewatched up to episode 3. I've also been listening to theories on YouTube. Amelia is behind all of this. She's the aunt they refer to. Wayne unknowing participates in her evil because he himself has blood lust. In fact they both get turned on by sex after violence, thus transforming death and murder into shared passion. I think Amelia is part of that cult. I also think that woman Roland was dating is connected as well.
This show is using a unreliable narrator as a plot device. Applying that knowledge, that would mean many things going on in this story are contrived. My theory is the case was solved in 90. He murdered a ton of people and then figured out Amelia was behind it. I think he killed Amelia. I think his son (if that's his son) and Roland and the interviewer are all not telling him the truth, because they know it would make no difference.
This show is about ghosts, it's about the evil deeds done in the name of justice, love and family, and how that evil never goes away. The ghosts from Vietnam followed Hays around, haunting him. Roland keeps saying, "I know who you are," indicating that there is a dark, twisted side of Hays that he can't get rid of. Roland himself is complicit in this situation because he himself shares those feelings with Hays. You see it all throughout episodes 1 and 2. Hays wants to kill and so does West; they're bored with nothing to do but kill time (another motif in this season). Roland suggests they leave and find someone to beat up. In episode 2 they torture the pedophile and Roland offers to execute him and bury him someone around the farm. This certainly indicates they've both participated in unlawful murder, and it appears they do it on a regular basis. This is why later on in another episode West says "I know what you done...what we done." This dynamic of being unable to escape the horrors and atrocities one has committed is illustrated in Woodards interrogation where he says "when I got out of the war, I didn't want to go home. I didn't want to go back to that old story. Have you ever had that problem, where you can't go and you can't leave?" This all ties into the incorporation of the theme of memory this season. Although his mind has forgotten many things, he keeps relieving the same case over and over and over again. Why? I believe because of the murders, and especially Amelia's murder. And so Wayne has done this before. Roland knows this and so does Henry, which is why they convene in the kitchen while old wayne is looking at Roland's hats. I think Wayne is stuck in a loop where he keeps going through the same motions with this case. His mind won't let it rest because of what he's haunted by. Somehow he wants to change the past and he never can. Again, Wayne wants to get a badge and gun and pretend he's a detective again. It's all a pretend game, both literally and figuratively. This is alluded to in the beginning of the conversation with Roland at the end of episode 5. Where he asks Wayne why he came and if he thought he would just come over and say 'hey partner, let's go play cops and robbers. It's also referred to in the first episode where they joke about pretending to be detectives and Wayne nudges Roland into putting the blue cop light on. At the end of the day they are just two men who want to sit around and shoot the shyt (kill vermin in the first episode). Now with Amelia being the killer and being killed--this is alluded to too many times. Most notably when Roland asks Wayne if he ever thought about getting married. Wayne responds I'd never want to put a woman through that; and the very next thing we see is the fox. Also rememeber Wayne keeps having to deal with his ghosts. Each time they show them it's alluded that they are the ghosts of the people he killed. Rememeber, one of the ghosts is Amelia. He tells her to shut up.
All in all, I believe Wayne finds out Amelia is behind it. I think she kills someone else as well. The trauma that occurs from him having to kill his wife is what has slowly caused him to forget the deeds he's done. He hasn't forgotten them at all, more or less he's just running away from them. Note that whenever Becca is brought up Henry acts strange. I am starting to believe she may be dead as well. Either way nothing is what it appears to be. Amelia didn't die in 2011, she was killed in '90. Wayne doesn't see Becca at the funeral in 2011 because there was no funeral. He's created this story of his family and his life after '90. The reason Wayne is shown finally reading the book is subconsciously he knows the details were all there for him to figure out Amelia was the killer.
This show very much feels like a serialized version of Shutter Island. Imo it follows it to a T. A war veteran who can't escape the horrors of what he saw in WW2 pretending to become a detective to bring down what he believes to be a conspiracy that killed Rachel Solando. He creates this alternate persona of himself as Teddy Daniels and not Andrew Leddis, because like what we will see in True Detective with Wayne, he cannot bring himself to accept the fact that his wife killed their children and that he in fact killed her in his grief. There is this grand scheme to help Andrew come to terms with what he keeps running away from. And JUST like true detective he has a ghost (his wife) that keeps haunting him and telling him lies. This whole thing is going to turn out to be a documentary about Vietnam vets with PTSD and how this contrived experiment can help them leave the horrors of what they have seen behind. This mirrors the same exact thing in Shutter Island where the experiment was the testing of a new theory by the main psychiatrist on shutter island. Now that I'm thinking of it, I don't think that that guy is his son at all. I think Amelia killed his family and he killed her in retailiation.
If I'm right--which I know I am-- get ready for the boo birds to come out after the season finale. There are going to be people pissed about the shows ending, and they are going to compare the fukk out of this to Shutter Island and claim it was a rip off.
I think whoever wrote this season got in over his head. He tried to do this contrived plot with multiple time lines to exercise a theme, and ending up getting lost in the overall structure of the story and the show. Season 3 story reminds me of something you would read in a literary novel. It just doesn't translate to TV. The writer/s should have gone back to the drawing board. The structure of the show and the jumping from timeline to timeline absolutely overshadows and even suffocates the spectacular acting performances being put on display here. Mahersala, Stephen, the lady that plays Amelia and the man who plays Tom the father should all get rewards for their acting in this show. Unfortunately whatever accolades they end up getting won't overcome the frustration and disappointment with how this season played out. The story itself is good, but it's execution is very poor, along with it being extremely predictable because the idiot director put too many clues in the first episode. He shot his wad. A better director would have known how to hold off and spread the clues of what actually happened, letting it build with momentum. There is no momentum going on here. The most we have is Roland agreeing to being partners...and a anonymous phone call from Julie.
Anyways, for those saying they're disappointed, I don't blame them. I kind of am too. I could be wrong with this theory, but I don't think so
