Oh dear God, that episode was information overload. I think my head is spinning.
No, seriously, my dad and I just sat here for about five minutes with gobsmacked expressions. EGAD.
--Mrs Hudson's backstory! Double murder! Drugs! Whirlwind romance! Shot someone's head off!
--John's backstory! Three years in Afghanistan! Qandahar and one other place I can't recall!
--ACD Canon references galore! Cmmdr Sholto! CAM appears again!
--BBC canon references, some of which we don't actually know! "Remember Red Beard!" (WTF, Mycroft?) Sherlock's mum! Irene Adler! Mycroft on a treadmill! (And with an "M" on his collar.)
AND SHERLOCK DID A PIROUETTE. Do you know what my dad said to me afterwards? "You need to write about that pirouette." "Dad, someone already did."
For a weird, wandering, seemingly pointless episode, dear god there was a lot going on. I'm kind of desperate to watch it again, and I have no idea when I'm going to be able to manage it.
AND THAT WAS SHERLOCK'S LAST VOW, AND MARY IS PREGNANT.
That's it, I'm done. My brain has gone into overload. Please leave your messages in the comments, and I'll try to get back to you as soon as I'm capable of rational thought.
Dear BBC,
Thank you for giving us a week between this episode and the next. It may take that long for fandom to recover.
Love,
Me.
