Hearing how Taj started out made Andy worry that something had happened with him - the things Taj had said about it being like his first orphanage meant that he hadn't thought it could have been something to do with his brother and now he was both kicking himself for being so selfish and cold with fear that Taj wasn't okay, and hadn't been all this time; the idea that he'd somehow not seen that was terrifying.
Taj spoke on though and Andy moved from fear to cold disbelief. The aftermath was bad enough to hear, but Andy's brain got hung up and stuck on the fact that his father had come back, that the man had laid hands on him and more yet again and that he, he must have gone willingly. Hadn't he?
He was shaking in Taj's arms long before he'd come to the end of the tale and he said nothing for a long while after Taj had finished. Eventually he sighed and then shook his head a little before giving Taj a tiny and brittle smile, incongruous against what he'd just heard. "Oh, well." he said and then shrugged, like it didn't matter that the darkest part of his past had reached it's claw out through the years and touched him, tainted him again.
