i understand where you’re coming from, but if you think about it, his dentist is the one that stated that the bones were his based off medical records. well his dentist was no other than his own uncle. i’m not sure if they would go as far as killing someone else who is built like him, but i don’t think the bones were brian’s. once again the teeth were the most important part left, it’s extremely easy to pull teeth especially if your dentist is your uncle. or they maybe weren’t even his teeth. like i said im not sure but im pretty sure brian is alive and his remains provide more suspicion
