I'll give that to you

Bellamy & Clarke in “Praimfaya”

Then in the scene where Raven is hallucinating herself floating, we can hear Jackson and Abby having a conversation in the background. I went back and listened to it because it was there for a reason and Jackson says “according to the record, Becca first developed what we know as nightblood for the Penal Mining Company”. He then goes on to say “criminals were put into hyper-sleep and given nightblood to protect against solar radiation”. Its not a lot of info but it does let us know a little bit about them. Those were the only hints that I caught, but there might be more.Idk if any of this is helpful lol but yeah this is all I picked up on

Roan be up in heaven like

Bellamy and Clarke are separated but they haven’t lost each other. They each carry the other in their head and heart. They are alone together… an oxymoron. 

The head & The heart

- JRoth in his TVLine interview

“Raven! We need to land this ship, now” Bellamy tells going to the others, using his heart instead of his head for the first time in 2199 days.
