In a Very Special Episode of The 100, we learn that lying and dishonesty to your friends are bad things and only lead to people getting hurt and friendships ruined.
We also learned that the writers must've watched The Lord of the Rings recently because that Octavia "death" was a straight copy of Aragorn's "death".
Luna has been a jerk since day 1, but she is a beautiful jerk.
I think the problem for Clarke is that there's been no breathing space for her to reflect. All of the Alie shit and...uh...someone's death... led straight into this radiation nightmare. She hasn't had time to think, only react. Her personality has always been that she knows what's best, since season 1, but she doesn't exactly have the people skills that makes a good democratic leader. Maybe she'll learn a thing from Jaha.
I was wondering why Echo looked guilty when Bellamy was bawling; I forgot that she and him had a history. I like her too, in part because she's one of the few characters whose motives you can't pin down. And yet she seems like she's probably a decent person.
