Theo didn't know where to begin at pointing out the gaping holes in what Zach had just said, wondered if maybe the boy had been purposely contrary to the truth, but he allowed himself to be distracted by the box. It might not have been a thing he would have said before he'd come to St Mungo's, but then those were also times when Theo had the mental capacity to try and be the person he wanted to be, not the one his father had made him into. He just wasn't able to disguise the rest of it under a mask of his actualised self anymore.
He reached for the paper as Zach unwrapped the box for him, reaching to pick up a scrap of it and rub his thumb against the shiny blue colour; his dirty fingers left marks but he seemed not to notice them.
He curled his hand back, paper still within, and stared in frozen surprise at the toy he was given.
He cast a wary but completely unbelieving look to Zach before reaching out to take it, his fingers stopping and just petting the fluffy ear of the stuffed horse instead. "You got me a thestral..." he said quietly. He wasn't sure how to feel about that. He didn't want to touch it though, but he couldn't stay away from it. "I, I'll make it dirty." he stammered, turning his hand over palm up to show Zach the mess, although he didn't look away from the toy.
