I think they both ultimately just wanted to be free. There was a scene early on where Capri looks up to the sky at a satellite, D asks her 'Why satellites?', and we never hear Capri's answer. But seeing the end, I think it was obvious. I hope they made it to the star they chased.

I truly love D so much man. The fact that his first time with Capri was the only time he didn't have nightmares was because it was the only thing motivated by him just having fun instead of the guilt and grief he had was so interesting to me
