[He would've moved back, maybe, if Gilgamesh hadn't caught him first. Drawn him into his arms, and refused to let go.

It's enough. Gilgamesh may want another, but he doesn't seek another. He just holds this man, more like a boy, in his arms, and comforts him as he would his own brother. He doesn't expect anything else, even if he may desire everything else. He just lets Setsuna hang there, as if he always belonged there, and hushes him before he can fly into another upset.]

It is alright. Do what you are able; live as you must. Keep striving. Never tell yourself no, I cannot be that, because I am telling you: you can.

[Gilgamesh wasn't one for pep talks. Usually, he'd just deride a target into submission until it gave in. But in this case, he's also trying beyond his means, as he urged Setsuna to do. He opens his heart even as every instinct rails against it. He shuts his eyes, sighs, and says...]

I am telling you, even if you've no love for yourself at all, I will love you anyway. I will believe in my knight, as I hope he should believe in me.

[What more can he relay to him? He buries his head in Setsuna's shoulder and very nearly wills him to heed his words, no matter what.]
