"Oh Connor, Conner, Conner.... you messed up." John said. "On the bright side, now I know I can't trust you... unfortunately, that means I can't just wipe your memory because if you find out about it again, you'd betray me."
Connor was begging, blubbering, and panicked... "What are you going to do?"
"I need loyalty, I need to know that you are looking out for me and can't betray me again. I'm sorry for this Connor but we are going to have a better relationship now."
"What are you..."
Connor's form shifted as fur sprouted across his body. "You're going to be my extra intelligent and loyal guard dog. You will love me and protect me, and not remember being human. Reality will change so mom and dad won't miss you, and after I've set up a life for myself, I may revisit what to do with you... Or maybe I'll make your bite infectious to people who aren't me, and you can grow me an army of annoying people turned into loyal, intelligent hounds... I'll have to think on that."
Connor was whimpering throughout John's monologue as he transformed. Suddenly his noises stopped and John looked up. Connor looked around, seemingly confused... John smirked, "Who's a good boy?" Connor stepped over and rolled onto his back with a happy grin as John gave him a vigorous belly rub.
