"Ah." He says simply and just kind of leaves it at that for a moment. There's a clarity to the previous conversation, suddenly, with Phillip saying that and Shido realizing that maybe normal humans wouldn't, or would think it was a blessing.

He's fairly certain, even in the tattered remains of his memories, that he didn't want to be immortal, hadn't asked to be turned. He remembers the church, the terror when he realized he wasn't going to be leaving it. But if he'd been given the choice, then, death versus immortality, he doesn't know what he would have chosen. He'd believed then that he was going to change the world, after all. Would he have naively thought he could hold onto his humanity from the beginning.

Would Cain have even let him have the illusion of it from the start?

He only remembers being human in odd, half-formed memories and in moments like these. It's a weird realization, to know this attitude also probably gives him away. But, also...

He turns and looks at Phillip, a bit more keenly, speculative,

"But you do. You also understand."
