[It's not nearly as warm as it was the first time. Eren supposes it can't be. They are, indeed, bound here by a promise. Neither of them intends for that promise to be broken. Eren should be glad for that. He is, in a way.

[He doesn't deserve to be hurt, really. He knows that too.

[He lowers his wrist. He wonders if they'll be watching the sunset through this window tonight, or if they're meant to be elsewhere.

[He takes Jeans hand at the wrist where his own band is tied; runs a finger carefully over the leather.]

These bands are a tradition from my home. They represent an eternal commitment. One that transcends even death. Bodies are buried with these wristbands still tied in place.

[Eren's gaze tries to catch Jean's; he'll stare right at him either way.]

Understand what that means to me, Jean.

You are my husband. [Eren pulls his hands away, now turning over that which wears his own wristband. He touches that band with two fingers, the same way he'd touched Jean's.] As long as I wear this wristband, that will never change.

This is more than a promise.
