WARNING: Spoilers for the True Detective season 3 finale.

Mahershala Ali) has slowly unfurled non-chronologically over past eight weeks on HBO, using his major unsolved case as a way to explore the power of memory and time in a wholly unexpected way.

In many ways, True Detective season 3 was a return to the style of season 1. That was somewhat clear from the start - the story is told across decades, focuses on the detective partner relationship contrasted with home life, has a southern American setting and hints of a conspiracy - but the finale proved things run deeper than that. As a vague and ultimately indirect crossover suggested, the end of True Detective season 3 mirrored season 1 in not being the victorious case closing that many online theorists seemed convinced it would be.

Indeed, while audiences did get answers to all the big mysteries of True Detective season 3's primary case in the bumper-length finale, the focus was most certainly on Wayne's life outside of (or, perhaps given his obsession, tangential to) the investigation. And that leaves many questions. Allow us to explain what the True Detective season 3 finale really means, and what makes the ending so effective.

True Detective Season 3's Case Was Easy To Solve (Because The Show's Not About The Case)

The clue is in the name. True Detective is ostensibly a mystery show. And so the thrust of season 3's story was that of the missing Purcell children, two pre-teens who disappeared on the day Steve McQueen died in 1980. The boy, Will, was found murdered and posed, while girl Julie remained missing until she reemerged unexpectedly a decade later in 1990. However, despite a new investigation, the real killer-kidnapper was never found. Throughout the eight episodes, a lot of clues were dropped pointing to food magnate Edward Hoyt (Michael Rooker), a pedophile ring conspiracy, and religious corruption.

In the True Detective season 3 finale, it was revealed that the kidnappers were Isabel Hoyt, daughter of the CEO, and employee Junius Watts. The former had lost her daughter, Mary, at a young age and gravitated towards Julie after seeing her at a Hoyt employee event. She started meeting the Purcell children in secret under the approval of their mother, Lucy (Mamie Gummer), but, after going off her Lithium medication, things went wrong: Will was killed and Isabel took Julie, who was raised as "Mary" in the "pink room" hidden deep under an off-limits part of the Hoyt estate. Watts helped Julie escape around 1990 and she later faked her death at a commune, ending up living happily with childhood crush Mike Ardoin.

In many ways, the twists are rather obvious if you've been paying close attention. It was clear Lucy had sent the note trying to curb the investigation and that Hoyt Head of Security Harris James had planted evidence in 1980. Hoyt Foods then slowly emerged as a malevolent force with ties to the death of far too many key players, while the big mystery at the company's core was the mental degradation of Isabel. The pink room sealed the deal in the final moments of episode 6, the same hour where an adult Mike was first teased. And yet, a lot of other clues wound up incidental; the straw dolls, an entry point into a conspiracy theory that tied the Purcells to season 1, ended up being simply toys. It could be argued that True Detective season 3's mystery is both easy and dishonest.

However, this shouldn't be too surprising to fans of True Detective: this is pretty much exactly what happened in season 1. There, a major, repeated cult of the Season 3 did draw connections to this story by teasing a bigger picture of cross-state pedophile rings, but that was again little more than a tease with no further exploration or relevance. In fact, it really just served as a reminder of what the focus of the show should be; in both seasons of True Detective (let's ignore season 2), the mystery and its potential threads didn't matter as much as the characters' stories.

The clue is in the name. True Detective is ostensibly a mystery show but it's really about the person who's tasked with the solving. The documentarian in the 2015 section working on a show called True Criminal is the one interested with total resolution of the case; the drama we're watching is much more about Wayne Hays.

Wayne Finds Julie Purcell... But It Doesn't Matter

True Detective season 3's story is told across three timelines - the original 1980 case, the 1990 reopening, and Wayne Hays' 2015 recounting for True Criminal - but it's primarily from the latter's perspective. The spark for the show is the aging, Alzheimer's suffering Wayne going back through his past memories to try and solve the mystery that dominated his life - directly and through his family - for decades. It's his attempts to complete the investigation despite everything that got him addressing his wife's death and reconnecting with Roland West, and indeed sees him complete his mission - even if he doesn't win or even realize.

After he and Roland discover the truth of Julie's disappearance, Wayne looks like he's finally getting closure - but something doesn't satisfy him. He revisits Amelia's book and comes to the realization - thanks to a mental apparition of his wife (wearing the same dress as from the bar proposal, no less) - that the girl isn't dead at all. He travels out to confront her, to get his Sherlock Holmes moment... and then forgets why he's there. What follows is a heartbreaking scene where Julie Purcell helps the man who's spent 35 years looking for her and neither seems fully aware; she has a moment of possible realization (she will have seen Wayne on TV), while daughter Lucy seems to recognize Wayne from earlier in the episode, but nobody states it. That dissonance is powerful: the audience now knows a complete truth but the protagonist is forever incapable of grasping it. We get actual closure but he will go to the grave not knowing.

And yet the show still twists this to be cathartic. This moment coincides with Wayne's reuniting with his estranged daughter Rebecca, resolving the other big mystery in the season and what a lot of Wayne's drive comes from; her absence from the show is rooted in his failing memory, leaving a hole in his life that can't be filled caused by a problem (his memory) that can't be fixed. The mystery was, in part, a route to that.

All that thematic foundation laid, though, for those overly invested in the mystery, True Detective season 3 does leave the door open for some more tangible resolution. After returning his father home, Henry (Ray Fisher) pockets the address to Julie's home - recognizing that his father did intened to go to that exact house - possibly to follow through on; his relationship with Elisa Montgomery of True Criminal opens up the possibility of the truth still coming out (whether it should at this point, considering everybody who missed Julie has now died, is another matter). Again, though, it's a final reminder that mystery resolution isn't the same as the detective's.

Amelia Was The Real Key To True Detective Season 3

Wayne can't be healed from his illness, but by the end of True Detective season 3, he is most certainly in a better place. Sat on his front porch, he's reconnected with both his former best friend and daughter and has a brighter future ahead. In the tranquility and watching two children ride by on bikes, he has one final memory. However, it's not connected to the investigation at all.

The show jumps back to Wayne and Amelia in 1980, just after their fight over her article on the incomplete investigation and his demotion that threatened to split their relationship apart at the start. They carefully reconcile, with Wayne sort-of proposing as they happily stumble out of the bar together. It's been a rough road and there are complications ahead - the 1990 sections of their marriage are fraught with resentment and a lack of trust - but this offbeat happy moment is what Wayne has been searching for the entire season. It's the kernel of their relationship, the point of no return, and, going by Wayne meeting her at school when they are both greying from earlier in the finale (she stays as a teacher despite everything), they ultimately worked it through.

It's been clear that Wayne and Amelia's relationship was the core of True Detective season 3 from very early on. Loss or regret appeared to be older Wayne's driving force, with her book an entry point into his memories; he was searching for Amelia, trying to combat the regret he feels about the turbulence of his relationship and gain some understanding of what really happened. It was this overt focus that led to the rather popular fan theory that Amelia was actually the killer. Instead, as intrinsically linked as the two's time together is to the disappearance, the truth is far less scintillating; they were two different people brought together and who fought for themselves and each other, eventually finding some happiness. It's a very real love story first and foremost.

What True Detective Season 3 Really Means

True Detective season 3 has many thematic parallels to season 1, but what it uniquely to the table is an exploration of memory, time and a sense of self. Wayne is dissociated from himself by his illness and feigning a sense of his personality, framing the story as one of rediscovery (a theme echoed in the simple reveal of Julie, who spent her childhood believing herself to be Mary) yet with an unsettling twist. The Wayne we see in the past, especially 1990, is a darker, more brutal figure than what we see confused in 2015; is this a result of him losing those bad memories or actual change? The handling of Watts, leaving him to wallow in his mistakes rather than killing him - as a younger Hays and West would have done without pause - suggests the latter.

That ambiguity can be explored deeper, but what the show obliquely leaves the viewer with is a view of changes over time. True Detective season 3 is set over a period of 35 years, a length of time that cannot be downplayed: it's twice as long as season 1 (which spanned from 1995 to 2012); it's how old writer Nic Pizzolatto was when he started developing the show; it's around HBO's median subscriber age. It's a lifetime to many and a substantial portion of a lifetime for everybody else.

This is the inherent tragedy of True Detective season 3: seeing a stretch of a life and discovering it incomplete and riddled with regret is haunting, bringing aging and loss to the fore. But True Detective combats that by showing Wayne healing through reconnection, fostering the friendships and relationships that had lost. It's a case of what really matters in life being the people around you.

True Detective Season 3's Ambiguity Makes It Great

However, everything discussed thus far is framed in a different light by True Detective season 3's final shot. After Wayne and Amelia leave into a bright lift, the show cuts to Wayne back when he was a soldier in Vietnam, alone and disappearing into the jungle. Unlike the fight for clarity of the previous eight hours, this final moment is incredibly ambiguous.

The Vietnam war hung over the 1980s portion of the season like it would any story of the era, and reemerged sneakily in 1990 through Hoyt and haunted Wayne still in 2015: is this the real unresolved conflict that underpins everything else? Is it, as some have suggested, a twist reveal that everything was in a young Wayne's head as a rationalizing for near certain death? Does returning to this point in a story that featured influences from Nixon, Regan and Clinton istration highlight the enduring scars of the conflict on America to this day? It can be any and all and none, a final talking point after a satisfying ending.

Except that ambiguity has been seeded throughout True Detective season 3. Wayne in 2015 has been plagued by visions and specters of those he's wronged or killed, but also the events of the past. As the season moved on, the past stopped coming in as memory flashes and instead bled over into the action, with the older man seeing his younger self; and the Wayne of the past (specifically 1990) would seem to be aware of the transition, at least for a moment. The unreliable narrator is simmering in the background of True Detective and never directly addressed, but with memory a core of the story the question of truth and of obfuscation remains (another potential Vietnam war parallel).

Indeed, for all the closure Wayne gets by revisiting his and Amelia engagement, we still don't learn their full story. The latest we see is the pair happy; her death and the influence on Wayne's emerging memory loss aren't touched on at all directly by True Detective season 3, creating a gap in a full perception of the narrative. Pizzolatto has revealed via his Instagram that Amelia died in 2013 of natural causes, but in the context of the show - and thus Wayne's perspective - it's got the same dramatic irony as Julie's survival.

What all this ambiguity does is ensure that, no matter how tight a reading on the core ideas and themes of True Detective season 3 one can construct, there's always some of Wayne's life that's out his and the audience's reach. The exact truth of a life can never be known, perhaps even to that person and definitely through a single event. The clue is in the name.
