when darc walks out of bunker or whatever with ely her holds her limp in his arms, her legs arms and head dangling he holds her with one arm under her knees and the other around her back, infront of himself

ely is upset and grateful, she is happy she is safe and alive but sad that her brother got left behind, she is in tears of rage and sadness as darc carries her away

but this also means that ely is now detached from the timeline of the watches power (which darc is not aware about)

darc returns to a spaceship he had hidden away for all these 10 years and uncovers it, ely and darc get inside and head toward the heavens
