This key detail you definitely missed from 'The Haunting of Hill House' finale could change everything

Like many horror fans out there, I binge-watched The Haunting of Hill House as soon as that sucker made it to Netflix - not just so that I could find out the secrets of the Red Room as quickly as possible, but also because I wanted to indulge in the sweet, sweet fan theories that would undoubtedly spring up soon after.

And, sure enough, there have been plenty of hidden Easter eggs and obscure details to pore over in recent weeks.

First, there were all those ghosts we somehow missed; then, there were the well-hidden hints about the truth of the Red Room that had been hiding in plain sight; and now it turns out that the last minute or so of finale may have held a lot more significance than we previously realised.

According to Oliver Jackson-Cohen, the actor who plays Luke in the series, the colour scheme of the last few scenes hints that the ending isn't quite as happy as we perceive it to be.

Throughout the show, there are hints that the Crain children are in the red room through the colour palette of their setting.

"We have been in this room, so many times and we didn’t know. All of us," Nell tells the others in the last episode. "Mom says that a house is like a body and that every house has eyes and bones and skin and a face. This room is like the heart of the house. No, not a heart, a stomach. It was your dance studio, Theo. It was my toy room. It was a reading room for mom, a game room for Steve, a family room for Shirley, a tree house. But it was always the Red Room."

And in each of their scenes, there's a red item.

"There’s this thing that happens when we’re all in the Red Room," Jackson-Cohen explains. "Whenever each child, each sibling, is in the Red Room, something in the fantasy is red. And it’ll be a very, very small thing. For Luke, when Luke gets taken to the hotel room, he’s worn Converse throughout the show, and all of a sudden his Converse are red."

But you know what else has a splash of red in it? Just take a look:

Jackson-Cohen says that it was Kate Siegel, the actress who plays Theo, that realised the significance in the cake's icing being red.

"[Siegel] went, ‘The cake is red.’ And on set I went, ‘Oh, my God!’ And she went, ‘I don’t know!’" he said. "And I asked [creator] Mike [Flanagan], and he went ‘I don’t know.’ And so I can’t tell whether or not I’m just crazy with this — or whether or not it’s something that could have legs."

Flanagan has yet to confirm whether or not the red cake is a sign that the Crains are still stuck in Hill House, but, given the tragic fates met by Nell and her parents, it doesn't seem far-fetched to imagine that Luke, Theo and Shirely are also stuck in the Red Room for eternity.

After all, it worked so hard to get them all there - why would it just release them so easily? I guess we'll just have to re-watch it all *again* to see if the theory holds up...
