Seok-go (Ryoo Seung-beom) is a quiet and seemingly unassuming maths teacher living alone in a Seoul apartment block. Deeply enamoured with his neighbour, Hwa-seon (Lee Yo-won), he visits the cafe where she works each lunchtime without fail - always ordering the same takeaway food - but, try as he might, his shyness repeatedly prevents him from connecting with her on an emotional level; managing only an almost embarrassed 'hello' and 'thank you' he walks away frustrated and unfulfilled on each occasion.
On hearing a commotion coming from Hwa-seon's apartment one evening, Seok-go knocks on her door to ask if she needs his assistance only to find that she has killed her ex-husband in a vicious struggle and is planning to hand herself in to the police.
Seok-go immediately suggests that, instead, he'll dispose of the body; help Hwa-seon to hide her crime and talk her through any subsequent police investigation.
However, before long questions begin to surface as to the true reasons behind his seemingly altruistic actions...

What would you be prepared to do for love? More than that, if someone told you they "did it for love" would you assume they meant love for someone or love from someone?
From the very moment we are first introduced to Seok-go as he awakens in bed hearing Hwa-seon talking to her niece outside her apartment, director Bang Eun-jin beautifully accents a link between the two main characters - a link initially only existing from Seok-go's point of view - and not only hints at his (too) deep feelings for a woman he barely knows but also foreshadows later revelations without directly stating their existence; thereby allowing for a feeling of hindsight when the true state of play begins to show.

In fact, scenes, narrative elements and character personalities having more to them than first meets the eye really is the order of the day throughout Perfect Number and in terms of Seok-go's persona we quickly learn that a simple maths teacher is far from what he is: For here we have an incredibly intelligent man whose analytical brain can seemingly plan for every variable, on the spot, in any given situation; a man who is utterly convinced that he can out-think anyone and everyone. As such, when he is brought face-to-face with the dead body lying on Hwa-seon's floor, he instantly sees the opportunity to kill two birds with one stone, if you will: By helping Hwa-seon to hide the murder (and her part in it) he's sure he'll be seen to be acting out of love - hopefully making her fall in love with him, in the process - and by meticulously planning for every eventuality that a police investigation may bring he will, at the same time, resolutely prove his superior intelligence and his ability to outwit anyone without even breaking into a sweat.

[s4e4] Edward Mordrake (2) May 2026

The episode reveals that Twisty was once a kind, mentally disabled carnival performer who was bullied by other "freaks". Falsely accused of child molestation, he attempted suicide by shotgun, which resulted in him blowing off his lower jaw—the reason for his iconic mask.

In a stark, gritty flashback to 1932 Berlin, Elsa reveals she was a successful dominatrix whose legs were brutally amputated during a filmed snuff movie.

The episode (Season 4, Episode 4 of American Horror Story: Freak Show ) serves as a major turning point that concludes the show's two-part Halloween special. The narrative focuses on the supernatural entity Edward Mordrake and his search for a "pure freak" to join his ghostly troupe. Plot Summary & Key Backstories

Mordrake evaluates several characters, including Legless Suzi , Paul the Illustrated Seal , and Elsa , but ultimately decides that Twisty is the one to join him. Mordrake stabs Twisty, whose spirit then rises with a restored face and departs with Mordrake's company. Critical Analysis & Themes
