I hope by that quote, that a couple's relationship is going to die.. not actually a couple dying together. 1 person is enough, let alone 3.
I feel terrible for wanting a character to die.. but if I had to choose, PLEASE be Artie or Puck. Or maybe even a parent like Sandy, he's annoying. Maybe even Terri. Or the irrelevant Mike.. he's a great dancer but that's basically all he's used for. Everyone else is fine and can stay where they are. As long as they don't get rid of Brittany, Rachel, Will, Sue, or Finn (all main/main-ish characters & fan faves so I doubt they would) then I guess I won't be too sad, but will still be pretty sad over the situation. They better make it dramatic as hell too, I don't want no Grilled Cheesus where it was sad, but not sad enough to start crying or anything.
