Norma Bates - Bates Motel
Much like Leonard Snart, Norma Bates isn't going anywhere on Bates Motel, but things will never be the same again. She is, after all, dead. No longer buried, of course, but dead nonetheless. Norman will keep a version of her around in his mind. But it's not the version we've come to know. She'll be completely constructed through Norman's many neuroses. Close, but no cigar.
Peggy Carter - Agent Carter
Peggy Carter was a feminist way ahead of her time. She founded S.H.I.E.L.D. and was a hero before there were capes and alien abilities out in the open. She was a woman fighting for equality in a time when no one would allow her the respect she deserved, but she demanded it, and kicked ass while doing it. We lost her twice this year. In Captain America: Civil War, modern day Peggy died, and Agent Carter was cancelled. It's a shame we won't have such an important figure on television anymore.
Grant Ward/Hive - Agents of S.H.I.E.L.D.
Will we miss the constant back and forth between Ward and Coulson? No. But we'll miss Brett Dalton, who officially left the show after both of his character's met their ends. Grant Ward was murdered by Coulson, then infected by Hive, who was then stranded in space with Lincoln in the final moments of the finale. The layers he brought to his characters, especially Ward, who went from agent, to traitor, to villain, in three seasons. For Skyeward shippers, they received no closure, and it's a shame.
Robin Hood - Once Upon A Time
Not so much because we love Robin himself, but we're going to miss Robin because we loved what he did for Regina. We loved their love story.
Brian Finch - Limitless
Limitless could have been just another procedural with a twist but it was slacker turned genius Brian Finch that sucked us in. It was the way that Brian’s mind (albeit with the help of a special sci-fi-type drug) helped solve crimes with the FBI that put a fresh twist on the spy game. We’re going to miss his cheeky smile and his almost sibling-like banter with Rebecca now that the show is gone.
Bash - Reign
Though Reign Season 3 and Bash's story has yet to end, it has been announced that Torrance Coombs will be leaving the series to focus on his new ABC show, Still Star-Crossed. Somehow the writers will write Bash out of their story, and it's looking to be through his death.
