The Governor Rapes Michonne
The despicable Governor of Woodbury takes Michonne, Glen Rhee and Rick Grimes prisoners. For Michonne, he tied her hands and feet separately and raped her mercilessly. This prompts Michonne to start crying for the Governor, to his surprise. She explains that the things she’s thinking of doing to him as payback scares even her.
Later on, she does as she promises and tortures him near to death.
