Goddess Nika came from behind her friend and she choked her with a pillow for a few seconds. Her friend peed herself as she thought it was an intruder or a serial killer who was doing that to her. But then the mistress let go of her and she was so scared that she had wet herself. And she did not talk to goddess Nika for several days because of that.
This woman had info that goddess Nika wanted but she refused to share with her. So she did not have a choice but to choke her to get it and so she used her bare hands to choke the woman who was so scared that she pissed herself. In addition, she gave goddess Nika more info than she wanted. She then let her go when she was done telling her what she wanted to know.
