Fenrir was amused by this bloke. He wasn't sure if he was just as dumb as shit, or if he was pretending, but it didn't matter to him. He really wouldn't be surprised if he wasn't mentally capable of much, that seemed to fit into the Brown girl's life fairly well, he'd even make a point of telling the bloke that at some later moment. "You see, kid, there's all sorts of magical ways for people in your world to communicate, I'm sure it won't be too hard to snatch one, but if you'd prefer I go directly to the source and tell her in person, I'd be happy to do that."
Fenrir stood over him with the others, listening to what he said. When he spoke, the others looked to Greyback for his reaction on that. Fenrir let out a genuine, barking laugh in response, quickly picked up by the others. "So, the bitch gets around, does she? Not surprising, she seemed real comfortable with you. I can easily see her spreading her legs to any bloke with a kind word." He was aiming for a soft spot, fairly certain he could rile the bloke up a bit. Really, it would be more fun that way.
