We already know that there is at least one more Holmes sibling, okay? And
we have been given Eurus, as the evil mastermind of season 4. Right? Don’t you
feel like something is, I don’t know, missing?
I mean, look, I’m not sure it completely adds up.
Are we to assume that Eurus is, in fact, Sherrinford?
Because I’m not sure it makes complete sense. What do we know
about “Sherrinford” really?
1) Sherrinford has done something that has caused Mycroft to deal
with him, possibly locking him away (”You know what happened to the other one”)
2) We know that Mycroft knows (or knew) where he is
(”Sherrinford is secured”)
3) We also know that he keeps in touch with him (the note on his
notebook clearly reads “Call Sherrinford”)
4) In theory he’s suposed to be the eldest sibling (though that
might mean little to the series)
What do we know of Eurus?
1) She probably caused some sort of trauma to Sherlock as a
child, something he might have repressed, was made to forget (we already have
evidence of memory supressing drugs this season)
2) She has been pretty much on the loose for some time, clearly
contradicting anything Mycroft has said of Sherrinford.
3) The only mention Mycroft has actually made of her was, from
what we heard of Sherlock himself, the infamous “The East wind will take
us all in the end [..] It’s a story my brother told me when we were kids. The
East Wind is a terrifying force that lays waste to all in its path. It seeks
out the unworthy and plucks them from the earth. That was generally me,” story
from his childhood.
4) We can assume that, most probably unlike Mycroft, Sherlock
does not remember her which is extremelly odd as, judging from Siân Brooke’s
(the actress who plays Eurus) age, she should be the youngest sibling. Memory
altering drugs? I’m guessing yes?
So what can we conclude?
Rationally, Eurus should be the third Holmes sibling we have
been expecting. It is the easiest explanation. Ockham’s razor (Ockham’s
sibling?) and all that. The name “Sherrinford” could be anything, from a code
name to an alias created to make sure no possibly traumatic memories of Eurus are jogged in
We know that Mycroft is actually protective of Sherlock. We know
that he has been keeping tabs on Sherrinford, possibly calling him semi-regularly, and
assuring everybody he is secure. And though we know he has been keeping tabs on
John too, trying to get him to help Sherlock, he does not seem aware of Eurus’
involvement with him. We might suppose that he’s trying to protect both his younger
siblings in his personal, convoluted ways, but then why the cautionary tale
about the East wind? Why the need to call “Sherrinford”, to check up on him? If
Eurus is Sherrinford and Mycroft knows she’s dangerous (and he MUST KNOW, hence
the cautionary tale) would he so casually risk John’s life by having them
interact when he obviously knows John is crucial to Sherlock’s state of mind?
It doesn’t seem likely.
So. Where am I going with this? I mean, is it completely out of
the realm of possibility that there are FOUR Holmes siblings?
This is Sherlock after all. Every other line is symbolism and/or
foreshadowing. Four cardinal winds. Four siblings.
And as we just found out: “people always stop looking after three”
And this is Sherlock and Moftiss. So, all I’m asking is: Should we stop looking after three? Perhaps not.
