what happened to mycroft in enola holmes

Mycroft Holmes doesn’t die or vanish in the story; he’s simply absent from Enola Holmes 2 because Sam Claflin couldn’t return due to scheduling conflicts, and the filmmakers shifted the focus to Enola and Sherlock instead.

What happened

• In the first film, Mycroft is Enola’s controlling older brother and initially tries to push her into a finishing school.

• By the end of that movie, Sherlock takes over as Enola’s guardian, so Mycroft is no longer central to her storyline.

• In the sequel, he does not appear at all, and interviews with the director said this was mainly because Claflin was unavailable, not because the character was permanently written out.

In plain English

Mycroft was written out of the second movie for practical reasons , not because something dramatic happened to the character.

What that means for the series

The creative team has said they’d be open to bringing him back in a future installment, so the door is still open for him to return.

TL;DR: Mycroft is still alive in the Enola Holmes universe; he just sits out the sequel because of actor scheduling issues.
