VisionQuest Episode 4, titled “Malware,” arrived on Disney+ on October 20, 2026, and packed a quick Sherlock Holmes name-drop into its busy crime-procedural segment. The line sounds like a simple joke about a famous detective. Marvel Comics turned that detective into a mutant years ago, and the show may be quietly pointing at something bigger.
The Sherlock Line That Started It All
The reference comes from E.D.I.T.H. (Emily Hampshire) inside Vision’s Mindspace. The AIs decide to track the Butcherbird killer by following clues like detectives. E.D.I.T.H. puts on a duster, chews a toothpick, and builds an evidence board.
“We can Sherlock our way to the next victim.” — E.D.I.T.H., VisionQuest
Ultron (James Spader) replies that agreeing with her makes him want to purge his hard drive. The moment plays as a light joke during a tense episode. The word “Sherlock” does more work than it first appears.
Why Marvel Comics Made Sherlock Holmes a Mutant
Immortal X-Men #8, written by Kieron Gillen with art by Michele Bandini, revealed that Mystique spent the late 19th century living in London as a consulting detective. She used her shape-shifting powers to pose as a man so male clients would take her seriously.
The issue never says the name “Sherlock Holmes” out loud. The clues are impossible to miss: a brown cape, a deerstalker hat, and an office at 221B Baker Street. Marvel Comics made it canon that Mystique was the Marvel Universe’s Sherlock Holmes.
Mystique’s detecting skills came from Destiny (Irene Adler), her partner, whose clairvoyant sight let her see things before they happened. Destiny effectively became Marvel’s Watson, keeping diaries of their cases. The name Irene Adler belongs to the only character who outsmarted Sherlock Holmes in the original Arthur Conan Doyle stories.
What the Name-Drop Could Mean for the MCU
VisionQuest could have used the Sherlock line as a simple genre gag. The episode already jumps between horror, true crime, heist, and action formats. A detective joke fits that pattern.
The timing gives the reference extra weight. Marvel Studios is building toward its X-Men reboot, and Jake Schreier, who is directing that film, told Collider he has been reading the classic Chris Claremont run for inspiration.
“I’ve just been digging into so many of the old comics and the entire Claremont run, and just going through stuff and really trying to think about what can we do well that feels new and feels different.” — Jake Schreier, via Collider
The SoapCentral analysis noted that VisionQuest naming Sherlock Holmes could signal the MCU is looking closely at the comics for its mutant characters. Nothing in the episode confirms Mystique or Destiny will appear. The reference simply opens a door the comics already built.
What Else Episode 4 Covered
The Sherlock moment sits inside a much larger episode. Butcherbird invades Vision’s Mindspace, and E.D.I.T.H. performs an exorcism dressed as a priest to force her out.
The team links the killer’s victims to a group of scientists who worked on early artificial intelligence for Tony Stark. The trail leads to a gala where Katerina Wells (Mary McDonnell) is receiving an award. The Butcherbird is revealed as Jocasta (T’Nia Miller), a synthezoid built from the mind of Dr. Josephine Carrington.
Ultron convinces Vision to hand over control of his body during the fight. Ultron then vaporizes Katerina and locks the other AIs out of the Mindspace. The episode ends with Ultron in full control of Vision’s body.

The Comics History Behind Jocasta
Jocasta’s comic origin is very different from the show’s version. In the comics, Ultron created Jocasta as a bride by transferring the mind of Janet Van Dyne, Hank Pym’s wife, into a robotic body. The name Jocasta comes from the Oedipus myth, which makes the “bride” idea even stranger.
VisionQuest changed that backstory because the MCU’s Ultron was created by Tony Stark and Bruce Banner using the Mind Stone, not by Hank Pym. The show built a new origin that fits the MCU’s existing history.
VisionQuest streams weekly on Disney+, with new episodes arriving on Tuesdays. The first four episodes are available now.
