Did VisionQuest Just Reveal Where Ultron’s “Peace in Our Time” Really Came From?

SPOILER WARNING: This piece discusses VisionQuest Episodes 1–4.

Theory Board status: INFERENCE (the lines exist and line up) · THEORY (that the phrase is Carrington’s) · Confidence: Medium

More than a decade ago, Ultron’s “peace in our time” became one of the MCU’s creepiest catchphrases. In Episode 4 of VisionQuest, it turned up in a conversation about a dead scientist — and the show didn’t explain why.

Here’s the moment. At the “Re-Evolution of Man” gala, Dr. Katerina Wells is cornered by the silver synthezoid who insists she is her old colleague, Dr. Josephine Carrington. Wells tries to talk her down: “I am not the woman that you knew. I’m trying, I am finally trying to create the world that you wanted. Peace in our time.”

The synthezoid answers: “Yes. Peace in our time. As last words go, I’ve heard worse.”

Three words, a lot of work. Let’s put them on the board.

What’s actually on screen

In Avengers: Age of Ultron, the phrase is Tony Stark’s before it’s anyone else’s. Pitching the Ultron program to Bruce Banner, he says: “This one, this very vulnerable blue one, it needs Ultron. Peace in our time. Imagine that.” Minutes later, the newborn program chews on it like a broken gear — “Peace in our time. Peace in our time. That is too much. They can’t mean… No.” By the time he crashes the Avengers’ party, it’s his: “I’m on mission.” “What mission?” “Peace in our time.” At the climax in Sokovia, he twists it: “This is peace in my time.”

VisionQuest knows all this. The phrase is in the archival footage of Vision’s opening monologue in Episode 1. And in Episode 4 it appears twice more, both times from Katerina Wells: once in a TV interview playing in Vision’s mindscape (“…to protect for peace in our time”), and once to Jocasta’s face, as “the world that you wanted.”

Also canon from the same episode: Markridge Biotech’s five-person team “created the first stable synthetic consciousness”; that research “was sold to, hello, Stark Industries”; and Stark “used the AI matrix Katerina sold him as the template” for his AIs. Carrington, the project’s co-lead, “died of natural causes in 2008.”

That’s the evidence. Now the readings.

Reading 1: It was Carrington’s, and it traveled with the code

The theory in the headline. Wells doesn’t say “the world we wanted” or “the world Ultron promised.” She says “the world that you wanted” — to the woman whose team built the template for Stark’s AIs. If that’s literal, the chain runs Carrington → Markridge’s matrix → Stark Industries → Tony’s lab → Ultron. Tony wasn’t coining a slogan in 2015. He was quoting the people whose work he’d bought, and Ultron inherited the motto along with the architecture.

The problem: the show has never told us Tony met Carrington, read her papers, or heard her say it. The sale has no date. Ultron, an episode earlier, insisted he was “a one-off.” And when he takes over Vision’s body at the gala, Jocasta greets him with “It’s so, so lovely to meet you” — not how you’d talk to code that grew out of your own.

Reading 2: It was Horton’s

This is the theory the fandom has run with. Several of the biggest Episode 3–4 discussion threads on Reddit (in r/marvelstudios, r/visionquest and r/Marvel) argue the phrase will trace back to Dr. Phineas Horton, the “real-life Geppetto” whose source code Wells calls “the genesis of all artificial intelligence that followed” — with Stark quoting the grandfather of AI, maybe as an in-joke.

It has real points in its favor. The gala is built around Horton’s exhibit; Wells’s own promo video runs the lineage “From the ill-fated Synthetic Man to the ill-fated Ultron.” And the timeline fits the phrase’s real-world history: “peace for our time” is what British Prime Minister Neville Chamberlain promised in 1938, after the Munich Agreement — exactly the era a Horton-built android would come from.

The problem: nobody on screen connects the words to Horton. The only person they’re explicitly tied to in VisionQuest is Carrington.

Reading 3: It’s Katerina’s PR line

The least exciting reading, and the one the show hasn’t ruled out. Wells is a CEO on a guilt tour. Her gala falls, as Thomas points out, on the anniversary of Sokovia. On TV she’s asked whether her company’s breakthrough caused it, says “Do I feel guilt?… No,” and then, in her speech, says “Yes, I do.” A woman rebranding her company’s worst invention might well adopt its slogan — and tell a ghost it was her dream all along.

The problem: “the world that you wanted” is very specific to say to someone you’re trying not to be murdered by. And Jocasta’s “Yes” reads as recognition, not correction.

What hasn’t been established

To be clear about the board’s limits as of Episode 4:

• No one in VisionQuest says who first said “peace in our time.”
• We don’t know when Markridge’s research went to Stark, or whether Tony and Carrington ever met.
• The synthezoid says “I am her”; the show’s own AIs say her AI is “based on” Carrington. Whether her memories of Carrington’s dreams are real is part of the mystery.
• We see Ultron hear the line; the show hasn’t told us what he makes of it.

What would settle it

A flashback to Markridge, Stark’s lab, or Horton’s workshop. Ultron recognizing the phrase as someone else’s. Or Jocasta explaining what Wells “took” from her. Any of those would move this card up to CANON — or knock it off the board.

Until then: VisionQuest opened its season on Ultron saying “peace in our time,” and four episodes later told us it might not have been his to say. That’s a pin in the board.
