Sarah had sex with Preacher
Earlier I had some doubt that whether Preacher had sex with Sarah. I happened to watch the movie again, and this time I came to conclusion they had sex.
Sarah says she wanted to thank preacher for saving her daughter and in any way he wishes to.At that time she was ready for sex and had come pre planned about it. She was already attracted to him and also confesses to her daughter later that they both love him.
Sarah was afraid that Preacher would also leave him like his husband, but for one last time she wanted to be with him.
She kisses Preacher and was about to leave, but then after hearing voices, she closes the door and comes back to Preacher. She could have gone outside and close the door and need not come back.She asks preahcer who is he in real (A priest or a Gun slinger)but he says that does it really matter. Sarah also feels the same and comes closer to him. This indicates a sexual encounter.
She was not interested in Hull. Only when Preacher left them, to collect his Guns, she thought that he wont return so she agreed to Hull's proposal.
She said, she didnt want to wake up in night with memories of Preacher,so for once she wanted intimacy with him.
All this clearly indicates, that they had sex. And Preacher wont mind having sex with a mature women like Sarah. He knew that she didnt love Hull and had come to him.
