Something's off about this scene...
All spoilers are unmarked.
- The ending of "Sardines", especially given that one of the characters, Rachel, is claustrophobic. Imagine being claustrophobic and hiding in a wardrobe stuffed full of people, one of is your ex and one of whom stinks, with barely any space. Then you hear someone outside the wardrobe locking its door, and a voice singing a song about sardines, and you can smell petrol fumes...and then the wardrobe bursts into flames, and you're trapped inside, with no means of escape.
- "The 12 Days of Christine": The eggs being thrown from nowhere in Christine's flat and the stranger with the raincoat who keeps appearing to her, and seemingly trying to kidnap her son.
- "Cold Comfort": George making his way up the hallway on one of the CCTV cameras which is playing alongside the creepy still-image of him being shown on the other camera. All whilst the sound of a disconnected phone plays.
- "La Couchette": When the dead man's corpse pops out of his bunk, scaring Shona and Hugo.
- "Tom and Gerri": The sudden close-up of Migg's corpse in the bath.
- "The Harrowing": Any scene at all that features Andras/Castiel.
- The beginning and end of 'Séance Time'. At the beginning, the audience is led to believe that the séance is real, making it genuinely chilling until the reveal that it's part of a hidden camera show. And at the end, it's all played out for real.
- "The Understudy": Jim's hallucinations, seeing drips of blood that grow into pools, and blood dripping out of his own eyes.
- The twist ending to "The Devil of Christmas", which reveals the entire production to be a secret Snuff Film where the lead actress is killed by the person narrating the footage.
- The entire second half of "The Riddle of the Sphinx". Everything starts to go rapidly downhill after "Nina" is paralysed by the pufferfish toxin.
- The Wham Shot in "To Have And To Hold", which reveals that Adrian had been keeping a sex slave in a secret room in his basement for nine years.
- Only a few minutes of "Dead Line", the live Halloween episode, could be broadcast, as technical difficulties led to the audio cutting out. Except not. It's very convincing, but the viewer realises there's something wrong when a repeat of "A Quiet Night In" put on in its place seemingly gets corrupted within the first few minutes, and a skeletal figure that wasn't there before starts clawing at the window. After further "technical difficulties" messages, it cuts to the various cameras in the studio. What follows involves macabre clips from old programmes, a supernatural presence, and every variation of Nothing Is Scarier employed to nightmarish effect, culminating in a truly disturbing ending. Especially when a skeletal face attacks Reece towards the end.
- If you look closely, you can see people hiding in the studio, including a girl in a white dress just before a woman is murdered. Towards the end you see her again very briefly when Reese is in the dark.
- The Wham Shot in "Death Be Not Proud" of the rotten corpse of David's mother in the bath. In fact, the episode is made of this trope; it's one of the most disturbing ones yet, from the adult babies to Emily and David bonding over their love of serial killers to Psychoville's Mr Jelly doing a trick with a rabbit that goes horribly wrong. And by the end, Beattie has gone insane, murdered her boyfriend and put his corpse in the bath.
- The Reveal in "Thinking Out Loud" that Nadia has dissociative identity disorder as a result of her father abusing her mother. All those other characters we've seen, besides Bill? They don't exist. They're all personalities she created as a coping mechanism. Considering one of her personalities is a cannibalistic serial killer, one wonders just what she did when he was fronting...
- The Wham Shot in "Hurry Up and Wait" of the skeletal hand sticking out of Bev's baby doll while her parents are wondering what happened to Ryan. She killed him.
- Simon's death during the ending of Simon Says is quite brutal and a little bit stomach churning to look at especially on how long the scene lasts. It doesn't help that Simon was actually auditioning for the role of The Baron and looked to have willing to go full method in appearing to kill Gavin and trying to seduce Spencer. In a morbid yet heartwarming nod to the fandom, it is a nice change to have Steve kill Reece in an episode which isn't common with the roles often being reversed.
- In “Mr. King”, a teacher realises something’s not quite right about the school he’s been sent to. What follows is essentially The Wicker Man in a Welsh primary school classroom.
- The Wham Shot in "Nine Lives Kat" when Kat turns her daughter over and sees that she has no face.
- “Wise Owl” is plenty disturbing from beginning to end, but the animated scene of the owl flying out of the burning house and staring silently as a child horrifically screams inside stands out in particular, especially when you know what’s really going on.
- Jai realising all too late in "Love is a Stranger" that Vicky is the Lonely Hearts Killer when he spots a jar with severed fingers in it. All he can do is freeze and stare at Vicky in terror before she bashes him over the head with a hammer.
- In "The Last Weekend", Joe trapping Chas in a bathtub full of quick-drying cement and leaving him to be Eaten Alive by insects, in revenge for Chas driving his daughter to suicide...except it was a Bungled Suicide and she ended up on life support for nine years until her parents pulled the plug. Steve Pemberton's sudden switch to dead-eyed coldness is chilling in the extreme. Not to mention that he planned his revenge over nine years.
