You are not emotionally prepared for this new Sherlock trailer.
I mean, from the very beginning you know that you're not going to survive until January. Let's be real.
We see Sherlock planning on surprising John with his reappearance.
We see some GRADE-A Mycroft sass.
Not to mention the glorious return of our favo(u)rite self-centered high-functioning sociopath.
We see Sherlock return to Baker Street...
The entire fandom shared Mrs. Hudson's reaction, TBH.
Sherlock's back because London's being threatened by a terrorist attack.
BUT GUESS WHAT. THE BBC HAS ALSO GIVEN US AN INTERACTIVE TRAILER WITH EVEN MORE FOOTAGE.
You're definitely going to need a shock blanket.
