Gustavain props himself up on his arms and a bit of his knees, just enough to not crush Phillip entirely in the aftermath, but he's not inclined to go even as far away as his side right now, not when he can have a few more minutes of being inside and on top of him. He presses his forehead down against Phillip's cheek, into the side of his neck a bit, and just breathes for a moment. And then, soft enough that Phillip might think he'd imagined it,

"You know well there's no such thing as promises with me, but I'll try not to stay gone so long, next time," it's clear he doesn't mean the First, or the other places he's been or might go. Phillip was right that even if Gustavain is Azem, he's Gustavain first-- a splintered soul is not the only indicator of a person. But that statement comes out sounding a whole hell of a lot more Azem than Gustavain, down to a lilt to his voice that Phillip hasn't heard in thousands of years.
