"I told him that you were human. And my friend. And you're from another universe so it's not like you have to worry about the stuff a human from our universe would, anyway." And by the end of their conversation he was pretty sure that Alastair had been aware Arden wasn't a totally mundane human, on account of how he'd agreed to let her come to their house.
But he wasn't telling Arden that. He was telling her, "It doesn't work over the phone, anyway," because that was true. "And you can, like, leave stuff out or tell him something that's true but doesn't really answer his question." Getting around Alastair's truth-sensing was something all of Gray's brothers had honed to an art form, and Arden didn't even have to worry about him reading her thoughts! "Just try not to directly lie, okay?"
