Phillip's brow crinkles as the soul crystal clinks against the desk, letting it rest there for a moment before picking it up, make sure he's seeing it correctly. "This is Azem's crystal," he says, running a finger over one of the sharper edges as he takes it in, "I don't even think one for him should exist, and even if Hades thought he'd lose I can't imagine him just--"

Something clicks in his head at that moment, his gaze turning sharply upward towards Gustavain. Towards and past him, more accurately, past the outer shell that makes up his body and out towards his soul.

It's not as though he'd never looked at it before, touched their aethers together so they were intimately known, but trying to sense familiarity in one shattered soul among millions was an attempt he'd given up long ago. But when he looks for a particular kind of familiarity and a specific hue, however faded it may be, it's suddenly all too clear.

"...Oh," he says softly, bringing his gaze back to Gustavain's eyes. He's... genuinely not sure what to do with this.
