The screen fades to black and is replaced with a title card reading “Part Two: Claire”. It's been an undetermined amount of time since the wedding, I would guess a few weeks at most. Justine has come to stay with John and Claire, and we see she's regressed to an almost catatonic state as she can't do ANYTHING by herself. As they wait for Justine's taxi to arrive, John and Claire discuss Melancholia: a rogue planet that is due to fly by the Earth in five days. Claire worries it'll hit the Earth, but John assures her it's completely safe and it'll pass them by.
Justine can barely even walk, Claire
forced to guide her to the bathroom and bathe her. John is just
DISGUSTED by all this, and again I say: GET HER SOME FUCKING HELP! A
few days later Justine is beginning to get more functional, Claire
taking her riding again. Just like last time, Abraham will not cross
the bridge so Justine begins to SAVAGELY beat him with her riding
crop until Claire intervenes. Mmm, there goes all that sympathy I
had for Justine. Will that damn planet get here already? That same
night Claire sees Justine walking outside, almost in a trance. She
follows her, finding her lying naked on the ground and basking in the
moonlit grow of the approaching Melancholia.
