In the middle of all the returning legends and multi-role stunt casting, the purest piece of American Horror Story: 13 is a man who barely speaks and spends his screen time drawing blood.
John Waters plays Mr. Phibes, the personal physician to the mysterious Mr. Nas. Every week he arrives at the Apollyon, opens a bag that also contains live snakes, and extracts exactly thirteen vials of blood from his patient. Then he leaves.
That is not a supporting character. That is a statement.

The Name Is the First Clue
Mr. Phibes is a direct nod to Vincent Price’s 1971 camp-horror classic The Abominable Dr. Phibes. Waters has spent years joking that he has always been trying to steal Vincent Price’s career. Ryan Murphy gave him the part. The casting is so on-the-nose it almost feels like a dare.
Waters does not play the role as pure comedy. He plays it as ritual. The blood draws are precise. The number is never accidental. Thirteen vials. Every single week. The same number that keeps killing people in batches of thirteen elsewhere in the season.
What the Blood Is For
The show has not explained why Mr. Nas needs that much blood taken on a fixed schedule. But the surrounding details make the purpose feel less medical and more sacrificial. Nas lives on the 13th floor. He vomits black sludge the moment thirteen people die. Constance speaks about him with religious reverence. And the man responsible for draining him is a cult filmmaker cosplaying as Vincent Price’s most theatrical monster.
In the language of the series, Phibes is not treating a patient. He is managing a resource. The blood is being banked, studied, or offered. The snakes in the bag only underline the point: this is not a normal house call.
Why Waters Was the Only Possible Choice
Most of Season 13 is built on nostalgia — Jessica Lange cycling through her old roles, Evan Peters doing five characters, the Coven witches returning. Waters is the opposite. He has never appeared in the franchise before. His presence feels like Murphy reaching outside the usual circle for something that cannot be mistaken for fan service.
Waters has always specialized in the grotesque presented as glamorous. That is exactly the tone of the Apollyon. A rotting old man on the 13th floor who may be something far older and hungrier. A doctor who treats bloodletting like a weekly sacrament. The casting is not a stunt. It is the purest expression of what this season is actually about.
The Signal About Mr. Nas
If Mr. Nas were simply a sick, wealthy eccentric, he would have a normal doctor. Instead he has John Waters carrying snakes and counting to thirteen. That choice tells the audience more about Nas’s nature than any piece of dialogue so far.
Whatever is living on the 13th floor of the Apollyon is not human in any ordinary sense. The man who keeps him functioning is not a physician in any ordinary sense either. He is a keeper. And the blood is the price of keeping him.
The next episodes will decide whether Phibes remains a background ritual or becomes something more active. For now he is the quietest and most honest character in the building. Every time he draws those thirteen vials, the season reminds us that the real horror is not the returning stars. It is the thing they are all circling.
Thirteen Vials as the Season’s Quiet Horror Engine
John Waters’s Mr. Phibes does not need jump scares if the schedule is real. Thirteen vials every week turns blood into calendar. In a franchise famous for ornate violence, that kind of quiet repetition can be more unsettling than another set-piece kill, because it implies permanence. Somebody has to show up. Somebody has to draw. Somebody has to keep the entity on the thirteenth floor in whatever condition Constance requires.
This is why the phlebotomist role is structural. Constance can host. Ben can clean. Twisty can deliver mass death. Phibes converts the aftermath into inventory. Pair that with Queenie’s voodoo turn and the show starts asking a sharper question: is the body a temple, a weapon, a resource, or all three at once?
Waters is perfect for that question because he refuses solemnity. A lesser guest star would play the draws as tragic duty. Waters can play them as procedure with a private joke, which makes the system feel more alive and more corrupt. Watch the October episodes for whether the weekly count stays background or becomes a clock the audience can feel ticking under every other plot.
Frequently Asked Questions
Who does John Waters play in American Horror Story Season 13?
He plays Mr. Phibes, the personal phlebotomist and physician to Mr. Nas. The name is a deliberate reference to Vincent Price’s character in The Abominable Dr. Phibes.
Why does Mr. Phibes draw exactly 13 vials of blood?
The show has not given an explicit medical reason. The fixed number matches every other use of thirteen in the season and strongly suggests ritual rather than treatment.
Does John Waters appear in more than one episode?
He appears in the early episodes performing the blood draws. His full role across the season has not been detailed yet.
What do the snakes in his bag mean?
They reinforce that Phibes is not operating under normal medical rules. The detail is pure Waters and pure American Horror Story at the same time.
