Wilson eventually severed ties with the Family, but not before introducing Manson to Terry Melcher. Melcher’s disinterest in Manson’s music is believed by many to be the motivation behind the Tate murders. According to Atkins, "The reason Charlie picked the [Cielo Drive] house was to instill fear into Terry Melcher because Terry had given his word on a few things and never came through with them." Tex Watson confirmed this, saying that Manson told him to "go to that house where Melcher used to live" and "totally destroy everyone in that house, as gruesome as you can."
That’s the big one, but there are a few other inconsistencies. For instance, before they killed anyone in the house, Watson made Tate, Folger, and Jay Sebring lie on their stomachs in front of the fireplace. Sebring, upset that this put a very-pregnant Tate in an uncomfortable position, argued with Watson, and was shot for it. The episode also shows Watson shoot Wojciech Frykowski as he attempts to escape, when in reality Watson tackled him and beat him with the end of a revolver before he shot and stabbed him to death. Additionally, Kai says Folger’s final words were "I give up, you’ve got me," when Krenwinkel has said her actual last words were, "I’m already dead."
