I love the small Bellamy mention in this episode.
Though I was just saying on the Bob board, that I want to see a more balanced dynamic between these two after 6 years. They've both changed for sure, and I'm looking forward to a Bellamy that doesn't place his sister's happiness above all else, including his own. I definitely feel that Octavia came into her own in the last few seasons, and hopefully we get to see more of how she's grown/evolved during the 6 years too.
