Gabriel was cool, but he's been alive for over 200 yrs so it made sense he was cool with dying. Hard to believe it would take him that long to get good at the piano though.
Both Octavia/Echo have grown a lot considering everything that went down on Sky Ring, so the quick forgiveness of Clarke didn't completely bother me. Especially considering the change Bellamy made, although the execution of that change and how his death went down overall is still a big disappointment for such an important character
Didn't really think about Jasper/Hope being kindred spirits in growing up w/out their parents for the most part and hearing stories of The 100 crew
I think the writers kept the Dark Commander around because they wanted an antagonist like him to cause trouble, but also didn't factor in the multiple times Indra didn't kill him when she could would make her look bad. Him stalking Maddie in the helmet cam was kinda cool though
I know people are surprised Murphy has made it this long, but I'm also surprised a C-tier character like Nyla has stuck around this long as well. Cool that a brother/sister combo get to work together on the show though.
