Arden was not gonna like hearing this! At all! "We fight demons," Gray explained, "and obviously the demons don't like that very much. Our house is warded to the gills, they can't even find it. But...a long time ago, Raiden had this boyfriend who was staying with us. And he left the house one day and the demons took him. They tortured him until he told them how to find our house and get past the wards, and then they killed him. And then they attacked our house, and Castor and Daman almost died. And since then we don't let humans in our house. For their own protection as much as ours." Wait, there's more! "Like, Alastair doesn't even let Joseph come to our house, and he's been his partner for..." Gray had to think about it. "Almost forty years." YEAH.

"So it's up to you? I told him that since you're not gonna stay in our universe it's not the same kind of risk, but." Gray shrugged and did not mention that he had very slowly and carefully told Alastair that it was very important to Arden that everyone know she was just a normal garden variety human, or that Alastair had replied with, "Ah," followed by telling Gray that if he thought it was a good idea of course she was welcome.
