What if Justin was with Brian in the loft to help in case anything went wrong while he was experimenting with erotic asphyxiation when Michael arrived?

What if Justin found Brian instead of Michael?

What if Brian was in the shower (maybe w/Justin) having already succeeded in his experiment with erotic asphyxiation before Michael arrived but since the scarf is still attached to the rafter, Michael thinks Brian was going to attempt suicide and later tells everyone that he saved Brian's life?
