He told some of the story to Sapphire, though he admitted that to her at the start that Aurelia would tell her about the rest, as he wasn't going to divulge secrets about her abilities. The only thing he really kept from her was the collars, the rest was just played down a bit, though often not by much. Some of his own blunders, like with the gravity room, however, he played up, using game descriptions to describe parts as she was the only other being in this existence that would get the references.
