One would ask, why was Sébastien confident enough to r*pe Mimi without fears of being caught. Well, for starters, he took her as a slut. Even if she wasn't, he was capable enough to threaten her to silence. Unless she wanted to die, then she should speak.
But now, he was the one unable to speak as Fred and the other party stomped on him mercilessly. Both men didn't need to ask what happened having seen it clearly with their eyes; he was trying to violate Mimi against her wish.
Grace and Miriam went over to Mimi who broke into a sob, bringing her knees up to her chest. Arianna was concerned about her friend's safety and tried to check up on her but Mimi glared at her intensely, warning her with her gaze to leave. They didn't have much time left, nor would her sacrifice be for nothing.
