My money's on Captain Lance. Given the frenzy that happens online the moment anything SLIGHTLY bad happens to female or minority characters, I can't see them killing Felicity off because everyone will use the tired old "fridge" motif that's been so overplayed as to become worthless or the only black character or his wife. I love Diggle and Felicity, so it better not be them anyway! lol But based on his reactions, I think he'd be WAY more broken up if it wee Thea or Felicity and the width of the grave made me think there are two bodies in there or supposed to be two so I could see Quentin being buried in the same plot that Sara was supposed to be.
