"Oh... all of that." He wasn't really surprised at the fact that Aqua had decided to share it with Callie - he'd already told her some himself, after all, and one would think it would be the kind of story that would give Callie some faith. After all, he'd been a messed-up kid, just looking for some sense in a world that was literally trying to kill him, and he'd risen above it and become a happy, productive member of (a very small) society. He shrugged, though; he hadn't asked Aqua to do that, and he can guess from Callie's reaction that the attempt to reach her hadn't gone all that well. She was just too... riled for it to sink in.

"I wasn't going to say anything more about it, not unless you asked. It's still... not really something I like to think about, much." He'd been so uncertain at that point in time, so close to breaking. If Lupa hadn't found him, he probably wouldn't have survived another three months on his own, likely because of a monster he couldn't evade. As the Legion grew, changed, and rotated, fewer people knew about what he'd been like when he arrived, and he'd found he preferred that.

"But I was wondering something - at Camp Jupiter, we couldn't leave there, either, unless you got official furlough from the praetors or were sent on a quest by the senate. So why is the same thing bothering you so much here?" It's an honest question, because he honestly can't see any difference, except that the Greek camp was smaller than the Roman. But it was the same experience, wasn't it?
