!! The Original Series

* I love Dale Cooper and his nutty approach to investigating the murder - throwing rocks at things and using dreams. It wasn't until I read the first comment on [[http://www.ferretbrain.com/articles/article-167 this blog post]] that I realized why he does what he does. Basically, it's all a parody of SherlockHolmes and his rational, logical ilk. They claim to use science and rationality, but everything they do is based on insight and illogical leaps that happen to be true. Cooper uses the least rational investigating techniques on Earth, and he's equally as correct. It puts a new spin on his character - maybe he's actually GenreSavvy, and knows no matter what he does everything he does will lead him closer to the killer - {{Tropers/randomfanboy}}
** Cooper's techniques also ''[[SubvertedTrope don't work]]''. He's no closer to finding out who Sarah Palmer's killer is after the majority of the series than when he started. Cooper is a BunnyEarsLawyer of the highest order but his biggest successes in the series come from his actual detective work. One might argue he does throwing rocks and investigating dreams because, [[{{Pun}} well, he hasn't got a clue.]]
* Take a good, long look at the opening title screen. The outline of the misty mountain behind the Twin Peaks sign forms what looks like a woman's face, looking up. The shot is framed, from the beginning of the show, [[spoiler:to ''represent Laura looking out from inside the black lodge.'']]
* Gordon Cole yelling at Windom's bonsai tree might me another quirk of his, but he yells because of his deafness. But then [[Tropers/{{Notahandle}} I]] remembered that Cole's hearing aid may had picked up on the bonsai tree's bug, so in essence, he was yelling at the tree on purpose.
* Cooper's habit of giving people a thumbs-up to indicate his assent might initially seem like just another of his endearing quirks, but given that his boss is extremely hard of hearing, it makes sense that he would get into the habit of communicating non-verbally whenever possible.
* The very fact that Laura's line to Cooper in the Season 2 finale about when she'll see him again corresponds ''exactly'' to the length of the gap between that episode...and the upcoming Season 3. Seriously, it's almost as if the "premature" cancellation was Lynch's plan all along...and now he's paying it off! Well played, Mr. Lynch...well played.
* May cross with WMG but, "one and the same" doesn't mean the giant and the midget, is about the realm of Twin Peaks and the lodges. [[spoiler:BOB got inside Leland Palmer in a literal and spiritual way]] and much like victims of sexual abuse can become abusers themselves as is implied that [[spoiler:the spirit of BOB in Leland is what drove him to rape Laura]] and that [[spoiler:Laura being possessed by BOB in both senses mirrors her loss of innocence]]. What happens in one peak occurs in the other.
** It helps that [[TheSkeptic Albert]] describes BOB as the evil that men do.
** Think about the last episode, [[spoiler:Earle kidnaps Annie and Cooper goes to the rescue but Cooper has to enter the Black Lodge to face his fears that are as he mentioned in past episodes his faults as an agent which are shown in full detail, what follows is Windom Earle getting his head "fired up" by BOB and it finishes with Cooper coming back only with Annie consumed by BOB aka, the evil of men]]. What if something arguably more mundane happened that day?

* Donna has an in-universe one in the pilot as she puts together in a few seconds the fact Laura Palmer is missing from her seat, the somber announcement, the secret message being relayed to the teacher, and the mood in the room to realize her best friend is dead. Also counts as an especially {{Tearjerker}} AwesomenessByAnalysis scene.
* In the bar scene in the movie, a man is seen putting something put a bottle of beer and giving it to Donna, suggesting he roofied her.
* The [[GainaxEnding ending scene]] of the [[CliffHanger second season finale]] in its '''entirety'''. [[spoiler:The real, good Coop is trapped in the Black Lodge while [[GrandTheftMe his body has been hijacked by BOB]], whom need we remind you, is a demonic rapist serial killer that forced his last host to torment and murder his own daughter!]] Until the new season comes out, we have no clue what horrors went down during those 25 years. To make matters worse, time flows differently in the Black Lodge than in reality; [[spoiler:[[AndIMustScream it's unknown what 25 years in that place could feel like to Cooper]] ]] and [[spoiler:[[NotHimself what it could do to him psychologically]] ]].
** ''The Secret History of Twin Peaks'' and ''The Return'' [[spoiler: confirms this to be true. Major Briggs is murdered by Doppel-Coop, Dopple-Coop raped Diane, he may be the father of Richard Horne, he's involved in terrifying criminal activity across the country, and regularly commits murders which he's smart enough to clean up after. In short, he's been a one-man plague on humanity for the better part of two and a half decades.]]

!! The Return
[[folder: Fridge Brilliance]]
* You know the series catchphrase, ''Who Killed Laura Palmer''? The one that there are posters and t-shirts of? Well, think about the DoubleMeaning: In the original run, it's revealed [[spoiler: BOB killed Laura, in the form of Leland. Or was it Leland himself following his darker impulses? ''The Return'' and ''Fire Walk With Me'' both lend themselves to an ambiguous interpretation. Especially since in ''The Return'', it's shown that BOB can let someone do bad things while in full control of themselves as he simply latches on and feeds on the ensuing suffering.]]
** There's also the harrowing implication that the negligence of Laura Palmer's friends and community members "killed" her by ignoring all the warning signs of what was going on: up to and including authority figures in the community like Jacoby, who seems to treat his patients more as victims to taunt and provoke - and even her own mother, who is completely oblivious until being [[spoiler: overtaken by JUDY]], another Black Lodge spirit who seems to have it in for Laura. [[spoiler: does JUDY kill Laura as well? The ending of ''The Return'' leaves the question up in the air]].
** Then there's the spirits of The White Lodge, who may have [[spoiler: created Laura as TheChosenOne]] and set her up to [[spoiler: die in a HeroicSacrifice]] without her knowledge after a lifetime of suffering. So, in effect, ''they'' [[LightIsNotGood killed Laura Palmer as well]].
** The Chalfonts/Tremonds seem determined to "kill" Laura Palmer in their own indirect way [[spoiler: by letting a doppelganger/tulpa of Laura Palmer roam around unaware of her identity]] and prevent her from ever finding out. They are entirely justified as it's hinted [[spoiler: there are some very nasty consequences when she does]].
** The ending of Part 18 implies that [[spoiler: even Cooper has some hand in "killing" Laura by, what appears to be, accidentally erasing her personality after trying to save her.]]
* Dougie Jones is said to have "episodes" where he "spaces out" so it makes sense [[spoiler: people don't necessarily react to Agent Cooper's catatonic state]] the way normal people would. Indeed, the one person who does react to it with an appropriate reaction in the prostitute he was with, is someone who obviously doesn't know Dougie very well.
* Mister C's rampage across the entire United States seems to strain credibility as it's very clear law enforcement agencies don't even know he exist until 25 years later and bad luck. This despite the innumerable bodies he leaves behind and the fact he has a criminal syndicate which includes everyone from rednecks to Las Vegas mobsters. [[spoiler: Then you remember Doppel Coop has all the memories of an FBI agent as well as BOB's supernatural powers as he displays in the prison. It's very easy to understand how he keeps off the radar of authorities now.]]
** It also makes sense [[spoiler: that he can do all this since he's ''immortal.'' The Woodsmen will continually revive him no matter what sort of violence he gets up to.]]
* Why does BOB let [[spoiler: Dopple Coop do the steering in their relationship? Well, BOB is all about feeding on the pain and suffering of his victims. In Leland's case, it was torturing Leland's own daughter for decades. In Dopple Coop's case, he has a endless stream of victims and terrified associates. Dopple Coop is just so much BETTER at doing evil than BOB.]]
* Lucy doesn't "get" cellular phones, and is confused and terrified when Sheriff Truman reveals he's talking to her from just outside the station when she thought he was calling from a fishing holiday in the mountains. It's a very strange moment, but recall Lucy's past behaviour, back to the original series' pilot: she's extremely specific about where things should be, and spends a long time explaining on which phone and which line calls will be coming through. The idea that someone she's talking to might be ''anywhere'' is entirely contrary to her lifelong worldview.
[[folder: Fridge Horror]]
* Heather Graham wanted to return to the series as Annie Blackburn but was told they didn't need her for it. [[spoiler: That's because it's very likely Bob and Doppel-Cooper murdered her as their first act upon exiting the Lodge.]]
* [[spoiler:So BOB and Mr. C have been essentially sharing a headspace for 25 years. The literal personification of evil, and an evil clone of a brilliant FBI agent, in one body. Imagine the horrific rampage that's been going on all that time. It was enough that Mr. C barfed up a huge amount of garmonbozia, anyway.]]
