- Differently from the book, Emily Brent gets a clear Alas, Poor Villain moment. While her accusation is the same as in the book (with the added implication that she was attracted to Beatrice), she suffers a breakdown when she hallucinates the girl she has led to death and spends her last scene alone, scared and saddened in the darkened parlor, after thanking Vera for a small favor, which is the only and last moment in which she speaks to someone else with genuine care.
- Although what he did to the hapless James Landor was disgusting and unforgivable, it's quite upsetting to watch William Blore's Villainous Breakdown near the end of the series. Especially with the buildup beforehand where he suggests that perhaps they are already dead, and being punished in hell for being involved with the deaths of innocent people. What Wargrave's victims are put through in the novel is inhumane and reduces them to animals. You feel sympathy for (most of) them, despite what they have all done to get there.
- Pretty much any flashback of Cyril's death can bring one to tears. In-universe, too, for the fishermen who tried to rescue him. It's doubtful that they even knew him, but they didn't have to — a small boy had been in danger, they hadn't been able to get to him in time, and he died. The grief on their faces is absolutely heart-wrenching.
- The scene of Vera whispering for Cyril to swim for the rock, and counting down for him to run. Cyril always wanted to swim to that rock, and someone he trusted gave him permission. Someone who he thought could be his aunt. Talk about Be Careful What You Wish For Then Vera sits in the sand, placidly drawing, and waiting for the moment when she'd feign having to chase after her charge.
- It makes Wargrave's last scene with Vera utterly karmic. She's trapped by a noose, balancing on the chair she kicked over and begging for her life as Wargrave explains his plan to her. Wargrave eyes her coolly as she admits that she lied to the inquest, that she did kill Cyril, an innocent child, and that they should ally to frame Lombard. He pulls away the chair, leaving her to hang.
- Hugo's interactions with Vera after; he planned to move to London with his sister, Cyril's mother, and sell their beach view house. He shuts down Vera's suggestion that they could find a cottage nearby and picks up the hints that Vera killed his nephew on purpose. At the inquest, he confronts her with how he knows that Cyril couldn't have outrun her, and he may not be able to prove that it was planned murder but if he could then he would deliver the evidence to the courts. And if he was the one that told Wargrave, it's possible he was trying to find a way to find justice for Cyril.
