"Uh..." Iestyn chewed his lip thoughtfully. "Um. I dunno- you're not a serial killer?" He grimaced and spread his hands, looking at himself in the mirror for a moment. "Well, if we're getting serious... and I don't think you would, but, I might have trouble if you were taking drugs again." He looked at Henry. "I know you haven't told me a lot of detail about what you went through. I just don't like the idea of them, never have. Weed is okay, like, not all the time or anything, but like, Addy smokes it sometimes, I'm not bothered. I just don't like the thought of losing my mind, or watching you lose your mind like that."
He spoke in as non-judgemental a tone as he could, hoping that Henry wouldn't get hurt for him bringing it up.
