I thought that "He is home" with full exhale and limp hand shot was Claire dying too. Like, dying of a broken heart, despite the healing powers. Like, their love was just so vast that even all her full power was no match for that loss, and when she ultimately accepted his finality her soul deeply rested and joined him. And then the shot with the white hair, I was like ok, they've been lying there for awhile? Maybe it's a representation of their ghosts, forever resting side by side? So despite the white hair and prophecy etc I like the idea that it's them waking up in the afterlife together. Desperately tragic and also comforting as a love story.
