The surprising Doctor Foster mistake everybody’s talking about on Twitter

Warning: this article contains spoilers for the final episode of the 2017 series of Doctor Foster

The second series of Doctor Foster ended last night (3 October) and, judging by the comments on Twitter, it seems safe to say that the finale has left viewers incredibly divided – and up in arms over a glaring error.

It quickly transpired that Gemma (Suranne Jones) had not run her ex-husband down with her car, as so many expected – but she had ruined his life enough to leave him feeling suicidal. We watched as Simon (Bertie Carvel) attempted to throw himself into oncoming traffic before being coaxed back to safety by his vengeful former spouse – only for her to offer him a “painless” alternative.

That’s right: she set him up with a series of injections and told him what to do with them. But it wasn’t long before Gemma, ever fickle, had a change of heart: she rushed to Simon’s hotel room to stop him and promised that, while she could never “forgive” his affair, she could find a way to forget it for the sake of their son, Tom (Tom Taylor).

Little she knew, though, that Tom had other ideas. Sick of his feuding parents, he decided to run away from home and estrange himself from them entirely in the hope of carving out a new life for himself.

With his face plastered on missing person posters everywhere, Tom’s mother and father were soon doing everything they could to find him. And, in the very last shot, Gemma broke the fourth wall and addressed the camera directly as she called for Tom to come back to her. 

“I’ll always be here waiting when you want to come to back,” she said, “whenever you want to come back.”

Some were moved by the final scenes:

Some were confused:

And then there were those who weren’t impressed at all:

One thing viewers have agreed on, however, is their annoyance over a continuity error hidden among all of that viciousness and revenge.

A number of eagle-eyed viewers spotted a mistake in the flashback scene, which showed Gemma and Simon enjoying a glass of champagne in their garden back in happier times (because, yeah, they used to be happy).

So what’s the issue?

Well, not only did the cork change from a plastic one to a normal one, but it also seemed to magically transport itself from the bush/next door’s garden (where it ended up after Simon popped it, if you remember) straight back into his hand.

And that wasn’t the only thing bugging viewers; they also took issue with the fact that Simon – despite losing e-v-e-r-y-t-h-i-n-g – decided to keep that cork with him ever since they popped it. An old cork. Right there in his pocket.


Whatever people thought of the finale, there’s no denying that Doctor Foster has made its mark. Ever since the first episode aired, fans of the BBC One show have made it their mission to flood social media with complex theoriesearth-shattering spoilerscommentary about the original (oh yes, it’s based on a very old play indeed), and praise for the drama’s conversation about sexual assault and consent.

Which is why so many fans were startled when showrunner Mike Bartlett suggested that there will not be a third season of the show.

Speaking to The Sun, he said: “No, I haven't written a third series.

“The BBC has never ever put pressure on us to do more and it’s not that sort of show. You could see that at the end of series one. There was just as many people going, ‘Don’t do a series two’. It’s because people care and I love that.

“There’s a lot of trust that we’d only do more if there’s a story and a reason. So there’s no pressure to do more. We all just focus on the one we’re doing and that’s a massive amount of work for everybody.”
