THIS HAPPENED: http://www.buzzfeed.com/ellievhall/first-real-trailer-for-sherlock-season-three
So, being a sherlockian I totally fangirled and clicked it.
I am not okay.
This trailer is so important and so exciting and actually tells you stuff about the new series, it's brilliant.
This is the most important thing that has happened in the fandom in the last 2 years (in your face, Lewis). Asdfghjkl.
So, if you are going to watch it I suggest take some breathing exercises before watching, do not be holding anything with liquid or anything glass while watching, and after watching do not run outside screaming SEASON 3333333!.
I hope the link works this time, I didn't last time I tried this.
