Telling his story was and will be one of the great honors of my life. Thank you."

Dr. Derek Shepherd

Fans may never recover from this one. Derek Shepherd (Patrick Dempsey) — aka McDreamy, aka Meredith's one true love — died in a car accident in season 11. "The decision to have the character die the way he did was not a difficult one in the sense of, what were the options," show creator Shonda Rhimes said in 2015. "Whether Derek was going to walk out on Meredith and leave her high and dry, that was going to suggest that the love was not true, that the love they had for 11 years was a lie, and McDreamy wasn't McDreamy." She continued: "As painful as it was for me as a storyteller, the only way to preserve what felt true to me is that Derek was going to die in order for that love to remain honest." Since his death, Dempsey's character made multiple cameos in season 17, during Meredith's dream sequences.

Denny Duquette (Jeffrey Dean Morgan), who was diagnosed with viral cardiomyopathy, came to Seattle Grace as a patient awaiting a heart transplant. During his time there, he developed a romantic relationship with Izzie Stevens (Katherine Heigl). Through his medical ups and downs, Denny finally was next in line for a heart, however, the donor flatlined. In order to get Denny to the top of the donor list again, Izzie cut his LVAD wire, which forced her to manually pump his heart. After a successful transplant surgery (and a proposal to Izzie), Denny ended up dying from a stroke in season 2.
