Sherlock!!
Oh my god this episode was so good! Like, sometimes I'd forget my heart was scheduled to break at the end and just get lost in how fantastically awesome the plot was. I don't care what anybody says, Andrew Scott's Moriarty is a total pleasure to watch and I enjoyed every second of his screen time. Also, I loved the scenes with Molly.
As for the heartbreak, I didn't cry as much as I thought I would, but that was mostly because I had already cried my heart out watching Warrior a few hours earlier. I did let out a tear just before the opening credit, which was a new record for me. As soon as the show opened with that close up of John's face it was BOOM! Instant heartbreak. And of course the ending was super sad and I felt empty for long time after the episode ended.
I spent a lot of time thinking about the episode while trying to fall asleep. The question that kept coming back was how. How did Sherlock do it? How did he fake is death? I rewatched the episode this morning and I noticed the truck transporting squishier-than-asphalt-looking things and I went ah, so that's how. That, plus the fact that he asked for Molly's help earlier in the episode. That's good enough for me for the moment, I have enough not to go insane while we wait for the third season to air. ;)
