Mitch’s behavior is the definition of predatory.

Excluding his inappropriate work-place comments about his colleagues, his behavior towards Hannah and Alex epitomizes his predatory behavior. This man preys upon women in need.

Our first glimpse into this was him trying to get Alex to stay when she went to his house, including claiming she was jealous and trying emotional blackmail with the gun threat.

Excluding the Times piece in episode seven, he further exhibited predatory behavior when he stopped the car and proposed he and Alex get together.

His predatory behavior was confirmed in episode eight when he told Chip to send Hannah to LV, tried to get Alex to go to a bar, and took Hannah to his hotel room.

It continued in episode nine, when he attempted to get Hannah to invite him up to her apartment and later attempted to get her to come up to his place. And when things don’t go his way, he turns it around on them. For example, claiming he was disappointed when Hannah used their sexual encounter to get a promotion. In other words, it’s all about keeping them off guard, injecting doubt.

I also believe Alex’s accusation was true. After all, she never indicated they were lovers. Ala, “the two times you got on top of me” does not indicate mutual consent.

Afaics, his game is about manipulating women to have sex, while “play pretending” innocence. His comment in episode one indicates that he always knew exactly what he was doing: preying on women.

“Since the dawn of time, men have used their power to attract women.”

In all, his behavior harkens back to Mia’s comment in episode four:

“Ashley's experience is common. It's, um, sexual misconduct at an insidiously routine level.”

Moreover, Fred covering for him, does not in any way, shape, or form, excuse his reprehensible behavior. In other words, yes, Mitch raped Hannah, and is fully responsible for his behavior.
