* In "The Last Weekend", Joe trapping Chas in a bathtub full of quick-drying cement and leaving him to be EatenAlive by insects, in revenge for Chas driving his daughter to suicide...except it was a FailedSuicide 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''.

* The WhamShot in "Death Be Not Proud" of [[spoiler: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 {{Series/Psychoville}}'s Mr Jelly doing a trick with a rabbit that goes horribly wrong. [[spoiler:And by the end, Beattie has gone insane, murdered her boyfriend and put his corpse in the bath.]]
* TheReveal in "Thinking Out Loud" that [[spoiler: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 WhamShot in "Hurry Up and Wait" of [[spoiler:the skeletal hand sticking out of Bev's baby doll while her parents are wondering what happened to Ryan. ''She killed him.'']]
* [[spoiler: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 [[spoiler: 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 [[spoiler: Steve kill Reece]] in an episode which isn't common with the roles often being reversed.

* Jai realising all too late in "Love is a Stranger" that [[spoiler:''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 [[spoiler:trapping Chazz in a bathtub full of quick-drying cement and leaving him to be EatenAlive by insects, in revenge for Chazz driving his daughter to suicide...except it was a FailedSuicide and she ended up on life support for nine years until her parents pulled the plug.

* “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.

* 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 NothingIsScarier employed to nightmarish effect, culminating in a truly disturbing KillEmAll ending. Especially when a skeletal face attacks Reece towards the end.

* In “Mr. King”, a teacher realises something’s not quite right about the school he’s been sent to. What follows is essentially ''Film/TheWickerMan'' in a Welsh primary school classroom.
