I think they would have a great relationship if Octavia had gone with him to space.
On the other side ... do you think Bellamy could have prevented that Octavia became Blodreina if he was with her in the bunker?
I think Bellamy would never be okay with that arena fighting thing.
But how could he prevent Octavia to make the cannibalism decision?
Maybe he could have convinced her that she has to respect people's decision if they want eat the human meat or if they want to die
Whatever ... this scene was so hard to watch. Bellamy told her that he loves her, but she shows no reaction ... She was so damn ice cold
