4 clues that point to the conclusion of the 'Knives Out' sequel 'Glass Onion'

You can read our full ending explainer here, but ultimately, the killer turns out to be billionaire tech bro, Miles Bron (Edward Norton).

"Glass Onion" picks up a few years after "Knives Out," with Benoit Blanc (Daniel Craig) contemplating life at home during lockdown when a surprising case comes out of the blue. It's not long before the detective is whisked away to a Greek island owned by Miles.

But when the entrepreneur's closest friends arrive on the island, it quickly becomes apparent that there's some bad blood between them all, in one way or another. It all stems from the fact that Miles swindled Cassandra "Andi" Brand (Janelle Monáe) out of their groundbreaking company, Atmos.

To make matters even more intriguing, Miles isn't the one who invited Benoit, and it quickly becomes a race to figure out who's causing the chaos during the fun holiday weekend.

When Duke Cody (Dave Bautista) is mysteriously killed in front of everyone, Andi's twin sister Helen (also played by Janelle Monáe) also gets shot in the middle of a blackout while masquerading as her sister.

Although director Rian Johnson positions Miles as a potential victim of the unknown killer, the end of the film unmasks the billionaire as the one behind it all, as he tries to cover up his own dastardly deeds.

But there are four clear clues early on in the film that point toward the "Glass Onion" ending.

When the group first arrives at the Glass Onion mansion, they all reminisce about their antics through the years by the pool, and Duke recalls a moment where Miles nearly "pancaked" him when the YouTuber was driving by Andi's house.

Miles quickly interrupts to name-drop Anderson Cooper, suggesting that this incident happened outside the TV host's house when they were heading to a party.

But what Duke was actually referring to was the moment when Miles nearly hit him when he was speeding away from Andi Brand's house, after the billionaire had killed his former friend over the rights to their company and staged it as a suicide.

Cody knew it was Miles who nearly flattened him because of the billionaire's distinctive baby blue Porsche that he constantly brags about. But later, when Duke spots the press release about Andi's death on his phone, he quickly puts two and two together to figure out that Miles killed her.

That's why Cody blackmails his friend to push his brand further, and it's this that gets him killed.

Duke gets very drunk at the party, before choking to death on what seems like nothing. He's actually gone into anaphylactic shock due to the pineapple juice in his drink.

It's the perfect setup for Miles because Duke already told everyone how to kill him earlier on in the film. Before the gang even set foot on the island he makes a point of saying that he "doesn't mess with pineapple" because of his allergies.

It was easy for Miles to pass Duke a pineapple-laced drink without him being suspicious about it because he was already drinking quite heavily at the time. He had no reason to suspect that his friend was trying to kill him.

At the start of the film, Miles questions why Benoit is even on the island since he didn't actually send him a puzzle box, and the detective gets chatting with the billionaire over the hostile tension between the group and Andi.

Blanc even makes a comment that the isolated nature of the island and the murder-mystery party is a perfect setting for anyone with ill-intent to try and kill Miles "in the dark."

And because Miles is an idiot who has never had an original thought in his life, he realizes that this is the opportunity to get rid of Andi/Helen in the middle of the night.

Miles runs and hides behind a mirrored wall when the house goes into blackout mode — part of the planned murder-mystery party — but he actually got the idea from Blanc. He couldn't even plan a murder by himself.

Although Miles is the one who brings his friends to the island, it's easy to dismiss him as a suspect because surely that would be too easy, right? But let's not forget he knows the layout of the labyrinthian Glass Onion mansion, whereas his guests don't.

So while everyone is scrambling to get to safety during the scheduled blackout after Duke's death, Miles is the only one who really knows where he's going.

That's why he's able to sneak up on Benoit and Andi/Helen in the weird mirror room that looks onto the staircase.

None of the other guests would be able to figure out their way around the mansion to find such a good vantage point in such a short space of time in the dark. As soon as Miles pulls the trigger and shoots Andi/Helen, he's practically given himself away.
