I've... got to walk back through that door someday to a world where you don't exist.

Her face finally crumples against him, arms tightening around his neck as though with the action alone she can make that not true. The thought of it breaks her, and it goes against everything she believes, everything she knows to be true. Everything she lives, day in and day out. Every day of her life. If the world came to an end for Ethan, does that mean it will come to an end in her world, too? The saturation of rifts continues to be a real problem people do not have a solution for. Will she be faced with the exact same impossible choice?

The thought isn't one she wants to have. At the same time, it's as though she can't escape it. Her eyes shut closed tightly against the warmth of his skin, her fingers curling lightly into his shirt at the back. "It doesn't make sense to me, either," she says, her voice barely audible and barely steady. It ruptures with the weight of the truth, and the reality that he has lived, which is so different from her own. She shakes her head stubbornly against him because it doesn't.

It doesn't make sense to her. It can't.
