First things first: Spencer gave Mikey an unimpressed look and said, "You turned a couple of chairs into a zombie house elf barricade. I think Schechter hired you for a reason."
It was, of course, plausible that Ryan might not be experienced enough to notice the bindrunes. But that went against everything Spencer had ever known about Ryan's intelligence and every instinct he had at the moment. He looked at Mikey, mouth twisting down. "Maybe. I mean, you could be right, but. It just seems a bit weird." He took a breath and added, "You know when I wasn't sleeping, before? That was -- William found the bindrune, it was targeted to get me, and it had, like, bits of my scarf and knew exactly what to do to stop me from sleeping, and I just think it's kind of a bit of a coincidence to start straight after the Runes expert who hates me arrives in the castle."
