So a little backstory on the co-worker, let's call her Mary, loves to take advantage of people in every way she can. Her husband is a drug dealer of every kind you could ask and is in and out of jail constantly for his dealings and such. Mary needed more money as her husband was in jail so she got a roommate, who she somehow convinced to have a threesome with her and her husband when he is let out of jail in a week or so. That's fine so far, but then she tells me she had roommate sign a contract so that they can get her drunk and drug her, so that they can do the things they want to that roommate said she wasn't okay with doing. I told Mary that I'm not okay with this, that its rape and all she had to say was that is why they had the roommate sign the contract. I have no proof or anything to give to the roommate to let them know this is going to happen and I'm not sure what to do, but I cant stop thinking about it and I feel sick. I need some advice on what I can do to stop it, I do plan on telling the roommate but like I said I have no proof of any of this.
