Unless it's a sitcom... people don't usually die on sitcoms.
I just caught up on last week's episode of Vikings, and was very upset! If you watch the show, and haven't seen the episode yet, I won't spoil it, but they kill off a very main character. Very shocking. I mean, it makes for an "edge of your seat" episode, but I don't think I'll want to watch the show anymore after that :/ At least not for awhile.
