She says Tyson invited her to his apartment at 10:30pm one night to share a bottle of wine and unwind for a couple of hours.
Watson, who says she felt pressure to impress her boss, agreed to have a glass of wine.
When she arrived at his apartment, things got awkward.
Tyson, 60, who is a married father of two children, took off his shirt and shoes and walked around in a tank top undershirt, Watson says.
He then put on romantic music.
Watson says Tyson then took out a cutting board and knife to cut cheese for the both of them.
She says that before he started slicing the cheese, he took the knife and made a stabbing gesture toward her, which she took as a bad joke that was nonetheless intimidating.
It was definitely a very weird power move, she said
Watson says Tyson continued making suggestive comments that contained sexual innuendos.
He allegedly began talking about human beings needing certain releases.
Tyson also spoke of the difficulty of being away from home for months at a time.
When Tyson asked Watson if she needed releases, Watson says she told him a story about her being sexually harassed.
Watson says he was unmoved.
It was like talking to a wall, she says.
As she got up to leave, Tyson stopped her and asked her to engage in a Native American handshake in which both of them hold hands tightly, make eye contact, and feel for each others pulse, she says.
Tyson told Watson that the handshake was a spirit connection.
When Watson tried to leave, Tyson said he wanted to hug her and that afterward he would just want more.
Watson says that at that point she left Tysons apartment quickly.
The next day, Watson says, she confronted Tyson. She says she told him that she felt betrayed since she considered him to be a mentor.
Tyson is said to have responded to her by saying that she would never succeed professionally because she was too distracting.
He was making moves on her. And that earlier link, Tyson I think was lying, because the assistant did not give him a hug after she quit her job. Tyson on the other hand said she did.
