( Briefly he wonders how that works - if they had the original Yuji change something of his appearance, would the pretender be able to copy it? Dye his hair, maybe, get a piercing, anything to put distance between the two. It feels a little unfair, and not exactly the best of options, so he puts it immediately on the backburner, thoughtful. )

He wanted him to come about telling Geto things naturally, instead of having more things dragged from him without his will. He already knows too much has been taken from the boy, and he's oddly protective of him keeping the rest. Tentative work to force him to relax, careful bolstering of his mood, it's been almost paternal. )
