Doctor Who Vs. Sherlock: We’re Not So Different, You and I

Both close friends witness the death of the main character. There’s one character that is head over heels in love with another. Both the main characters die.  Both of the main characters aren’t actually dead. (We suspect nano-robots.) The woman doesn’t give a shit and also, loves guns. The villain is the “evil twin” of the main character.
