[His fingers curl in Byakuya's shirt, and he wants nothing more than to grab him and slam his head into the floor until there's nothing left but a bloody smear. Shirou needs Byakuya here, he does, if only to confirm his own existence. But if Byakuya can't even do that much, if he has to deny it as much as Emiya Kiritsugu has, then he doesn't have much use anymore, does he?

He doesn't, not at all, and with that, he grabs Byakuya and knocks his head into the floor.

But he can't get too carried away now, no, not yet, not yet at all, he needs to make sure Byakuya knows how much of a fucking liar he is before that.

Shirou doesn't understand why it's so difficult, why people can't accept Kotomine Kirei for who he is. Kirei's cruel, Kirei's a murderer, but it's not that bad, and Shirou knows his father loves him because he understands these things better than anyone else. They're just alike and precious to one another, and that's why Byakuya is full of shit]

Will you just shut up?!
