Theory Time: Who Is the Girl in Pink? (And Why She Might Change Everything in Young Sherlock)
I just finished watching Young Sherlock, and I have to say—this show completely pulled me in.
Not just because of the mystery, but because it fits perfectly into this new wave of modernized period dramas. The kind that keep the historical setting but feel incredibly current through direction, music, pacing, and character dynamics.
In many ways, it reminds me a lot of The Artful Dodger.
Different stories, same energy.
And like any good mystery show… it leaves us with questions.
So today’s Theory Time is dedicated to the biggest one of them all:
Who is the girl in pink?
The Girl in Pink: Coincidence or Clue?
We first see her in Oxford.
She’s sitting on the grass, reading a book, while Sherlock is working—right at the beginning of the story.
At first, she feels like background.
Just another student.
But then… she keeps appearing.
Not just in Oxford.
But in completely unrelated places:
During conversations with Moriarty
Near Beatrice’s grave
In moments where she shouldn’t logically be
And that’s when it becomes clear:
She’s not just a random character.
Real… or a Hallucination?
At first, it’s easy to assume she’s a hallucination.
But there’s one detail that made me question that.
When Sherlock is arrested and put into the carriage, we see the crowd behind him.
Everyone is blurred.
Except her.
She’s still there.
Visible. Present. Real.
And that’s important.
Because usually, when a character is just a projection of the mind, they disappear when the perspective shifts.
But she doesn’t.
Which leads to a first, crucial theory:
👉 She was real at least once.
And what Sherlock sees later might be his mind holding onto her.
Theory #1: Irene Adler… or Someone Like Her
If she’s real, the most obvious answer is:
👉 She could be Irene Adler.
The one woman who, in classic lore, leaves a mark on Sherlock.
But here’s the thing.
This series isn’t strictly following Arthur Conan Doyle.
It’s inspired by the novels of Andrew Lane, which already reinterpret Sherlock’s youth.
So this girl could also be:
👉 A completely new character 👉 A rewritten version of Irene 👉 A future emotional anchor for Sherlock
Because unlike the original Sherlock, this version feels more open to emotional connections.
And that changes everything.
Theory #2: A Reflection of Beatrice? (Probably Not)
Another possibility is that she represents Beatrice.
A mental image.
A projection.
But this theory doesn’t fully work.
Because when Sherlock is presented with the fake Beatrice, he doesn’t hesitate.
He believes it instantly.
If he had already formed a mental image of his sister, there should have been at least a moment of doubt.
A pause.
A mismatch.
But there isn’t.
Which makes this theory… unlikely.
Theory #3: The Unknown Girl in the Grave
This is the darker theory.
The one that feels almost supernatural.
What if she is the girl buried in Beatrice’s place?
The unknown victim.
The one no one is looking for.
The one whose identity has been erased.
Could she be appearing to Sherlock as a way to push him toward the truth?
It’s a fascinating idea.
But it also feels… a bit too far removed from the tone of the show.
Still, not impossible.
The Bigger Picture: A Story That Isn’t Over
What makes this even more interesting is that the mystery isn’t actually resolved.
Yes, the father dies.
Yes, we uncover parts of the Apostles’ plan.
But then we get the key.
And that key clearly leads to something bigger.
So whatever the girl in pink represents…
She’s tied to something that hasn’t fully unfolded yet.
Moriarty and Beatrice: The Rise of a Villain Duo
There’s another layer to all of this.
And it’s one I find extremely compelling.
The show is clearly building something between:
James Moriarty
Beatrice Holmes
Not just as individuals.
But as a pair.
Not driven purely by hatred.
But by something more complex:
👉 Envy 👉 Competition 👉 The need to not be second to Sherlock
And that dynamic?
Feels like the foundation of a true villain duo.
Not one leading, one following.
But two forces on equal ground.
A Mirror Dynamic: Heroes vs Villains
If that’s the direction the show is taking, then we might be looking at something bigger:
A mirrored structure.
A dark duo → Moriarty & Beatrice
A light counterpart → Sherlock & someone else
And that’s where the girl in pink comes back into play.
Because if the villains are being built as a pair…
Then Sherlock might not be meant to stand alone.
She could be:
👉 His equal 👉 His counterpart 👉 His emotional balance
A dynamic similar to classic storytelling structures, where two opposing pairs reflect each other like pieces on a chessboard.
So… Who Is She Really?
Right now, the strongest theory remains:
👉 She is real 👉 She will matter 👉 She is not random
Whether she turns out to be Irene Adler, a new character, or something entirely unexpected…
She feels like a key piece of the future narrative.
Your Turn
That’s my Theory Time.
But now I’m curious.
Who do you think the girl in pink is?
And more importantly…
Do you think she’s connected to Sherlock’s future — or to something much darker? 👀
