The actual situation was a progression. The RA "trainee" was told about noise coming from a dorm room, sounded like some in distress. The first time it was just a guy and a girl wrestling on a bed, but the next situation progressed to him holding her down and tickling her, then the girl (me, in this case) was tied up and not being tickled, then it progressed to tickling, etc. At various times I was told to either tell the RA responding that I was ok and to go away, then I was told to not say anything, then to not say anything but look panicked, etc. The trainee had to decide in each case how to handle the scenario, how to talk to the guy and the girl, etc. Also remember this was 1986 and attitudes about consent were still being evolved.
There were dozens of scenarios involving all kinds of potential problems, from roommates fighting each other to suspected drug use, etc.
