Look what you did to yourself, all those complicated little emotions
Mycroft: Sherlock, however hard that was -
Sherlock: Euros, I won. I won. Come on, play fair, the girl on the plane, I need to talk to her. I won, I saved Molly Hooper.
Euros: Saved her? From what? Be sensible, there were no explosives in her little house. Why would I be so clumsy? You didn't win, you lost. Look what you did to her. Look what you did to yourself, all those complicated little emotions, I lost count. Emotional context, it destroys you, every time.
