It's impossible to choose just one cry-worthy Grey's Anatomy episode, so here's a selection. So sorry, someone dies in every single one of them.
Season 2, Episode 6, "Into You Like a Train" – Two patients in a train accident are stuck on a pole together and it's absolutely devastating.
Season 2, Episode 27, "Losing My Religion" – Denny dies, and Izzie finds him when she goes to show off her prom dress.
Season 5, Episode 24, "Now or Never" – All you need to know is this: 007.
Season 8, Episode 24, "Flight" – The plane crash.
Season 11, Episode 21, "How to Save a Life" – This is the ep where Derek dies. That's all.
