Fantastic premier! New Clarke is awesome and I love the continued world building they are doing with the grounders. I am so glad that the focus of each main storyline is her, Bellamy, and John Murphy, who are my three favorite characters. I honestly love almost every charter on this show though, even Abby is getting better. I liked the stuff they did with her and Raven, even though I hope this whole surgery storyline doesn't last much longer.
Really the only character that sucks is Jasper, and he just needs to die already. I honestly don't think there is any hope of him ever turning into a good character the way John Murphy did. It also doesn't help that Devon isn't anywhere near as good of an actor as Richard Harmon is. I am just afraid they will kill Monty off for some crap reason so that Jasper can become this brave hero or something. Instead they should kill Jasper off and use that to give Monty more of a prominent role.
Anyways, despite the Jasper stuff, I am super pumped for the rest of the season. This series is damn good and I really hope CW keeps it going past this season.
