Connor Walsh - How To Get Away With Murder
Connor's attitude has caused him to be excluded. Connor's awareness of Annalise's mistakes makes him dangerous to have around and he's not afraid to confront her, at least before she scares him and forces him to back off by threatening to frame him for all the murders they've committed. This rivalry between he and Annalise could add a new element to the show, but with the tension between Wes and Annalise, is there really room for Connor anymore? He could've left, but Oliver deleted his acceptance letter to a new college. What's he going to do now? Is Oliver going to take his place?
Matt Donovan - The Vampire Diaries
The token human kept around for nothing other than that. Matt Donovan lost his sister, his mother, his ex-girlfriend(s), and the last decent relationship he had was with Rebekah Mikaelson, which ended when she left for The Originals spin-off. What does he do other than obnoxiously survive death after seven seasons? Matt should've died years ago. It's quite unrealistic that a human has survived through that much in Mystic Falls. Matt hasn't had a story since season one, at least a decent one that helped him grow as a character. Maybe it's time for him to go for good if he can't get that.
Rebekah Mikaelson - The Originals
Please come back, Claire Holt. Rebekah's time on The Originals has only been heartbreak and dying. When she comes back or returns from the dead, it's for an episode to further the bigger plot, and then she's staked in the chest again. She's suffered from so much heartbreak due to the hands of her family, Rebekah could be a great emotional instigator if Claire Holt ever chose to return permanently. Otherwise, the character is lacking at the hands of another actress.
Scarlett O'Connor - Nashville
Oh, Scarlett. Her entire story, including her recent musical success, has almost always revolved around Gunnar. She couldn't find success as a solo artist, she damn near lost her mind. Suddenly, with Gunnar, she's incredible and centered. Even her relationship with the hot doctor was destined to fail because she couldn't stop thinking about him. While her and Gunnar are an amazing pair, she doesn't even get scenes with her uncle anymore. Those stopped shortly after her mother's death, which hardly moved her.
Bash - Reign
Bash's time on Reign has almost come to an end. It's been revealed that after season three, Torrance Coombs will be leaving the show, and it's about time. Bash has been almost unbearably irrelevant to the story since season two. In season three, his mission has been to find a killer that haunts France and cuts his victims' hearts out, jarring them as a reminder. But once the entire castle becomes aware, the person to uncover the killer's identity is Catherine. Why is Bash even still around if his only story is going to be given to someone else?
Ray Palmer - Legends of Tomorrow
Ray Palmer is The Atom! Ray Palmer keeps falling into these unfulfillable relationships. First with Felicity, now with Kendra. His engagement to Kendra is bound to end in a messy way, as she is literally fated to be with Carter, or whichever reincarnation she meets. He has the potential to be a great hero, as we saw in Legends of Tomorrow Season 1 Episode 13, where he finally grew as The Atom, instead of miniaturized.
