8. Heather Brooks

Heather (Tina Majorino) had an unfortunate ending after searching for Richard (James Pickens Jr.), who she does successfully find. The intern gets electrocuted and collapses, bumping her head hard. She doesnt make it due to swelling in her brain. This is entirely Shanes (Gaius Charles) fault as he was the one who was supposed to find Richard, but instead passes the task off to Heather and takes her page from Derek.

After Izzie (Katherine Heigl) gets fired for making a mistake that puts a patients life in danger, she basically runs away, cutting off contact and leaving Alex Karev (Justin Chambers) to pay all of her medical bills. She only comes back when Meredith tells her that Alex is moving on. She wants to get back together but Alex knows he deserves better than how shes treated him. Hes on the other side now and while hes happy shes okay, he wants her to go and not come back. Rather than having these random appearances in season 6 until she leaves, wouldnt it have made more sense for Izzie to have been killed off in the season premiere? At least then her character wouldve been remembered in a good light. However, due to how she treated Alex, any fond memories of the character are left soured.

Lexies death is probably one of the most known and talked about deaths on the show. In the season 8 finale, we lose the character about 15 minutes after a plane crash and it is painful. Mark (Eric Dane), Meredith, and Cristina (Sandra Oh) discover that she is trapped under part of the plane. While Meredith goes to find Derek (Patrick Dempsey), Mark and Cristina try to lift it off of her, but its no use. Due to her injuries, nothing is going to help. Cristina leaves her and Mark alone to say goodbye but Mark is still in denial, insisting shell be fine.

Lexie (Chyler Leigh) tells him that shes dying and eventually, he gets down to the floor and holds her hand, saying that he loves her and has always been in love with her. The more he continues, mentioning how she has to stay alive because theyre going to get married and have two or three kids, the harder it gets to stop crying. Her last words echo his sentiment that they are meant to be. It was impossible to come out of the plane crash with zero casualties but well never be over this loss.

They were definitely meant to be and while we can have some peace knowing that Mark (Eric Dane) and Lexie are together, that doesnt make his death in the season 9 premiere any easier. Were now 30 days after the plane crash and he is still unconscious in bed, which means it is time to let go per his directive. Throughout, he is honored with flashbacks highlighting his friendship with Derek, how he took Jackson (Jesse Williams) under his wing, his love for his daughter, and more. The following episode even fills in the gaps and we get a proper goodbye thanks to the surge, referencing Marks final surge of energy before he gets worse. However, that goodbye makes the whole experience even rougher for the fans.

Callie (Sara Ramirez) wants to move to New York with her girlfriend, Penny (Samantha Sloyan), who received a grant, which sounds like a pretty great ending for the character. However, the problem isnt the decision or even the ending itself but what comes with it and how she goes about it. She wants to bring Sofia with her, not considering Arizonas (Jessica Capshaw) feelings on the matter. This leads to a horrible custody battle, which is especially difficult to watch if you loved the previous fan-favorite couple. Arizona wins and being the bigger person, she tells Callie to still go and that theyll figure out a custody schedule that will ensure everyone is happy. The entire storyline paints Callie in a really bad light and the whole thing was handled poorly.
