<human>: Summarize the given text in a few sentences.

My fiance just called and told me his roomate came into his room while drunk last night. Apparently he woke up and she was just standing there staring out the window in a thong. She was incoherant and got into the bed with him. He said he tried to tell her to leave but she wouldn't and he spent a few minutes trying to convince her to leave.  Eventually (~5 mins) she got up and he helped her into her room. I am in no way concerned about my fiances actions but his roommates actions are pretty troubling. He is the only male in an apartment of all females (all of them are in uni)and i dont want him to be accused of anything due to someone elses incoherance. It could be a one time thing but I dont know his roommates and neither does he. Somewhat of a last minute desperate living situation. I told him he needs to talk with her and be very descriptive of the actions he took. I also told him to start locking his door at night just as a precaution. I know it was probably just drunkness but i also know that men often get the short end of the stick in situations like these where the girl might get "confused" about what actually happened. I am in no way worried about my fiances honestly and i believe what he says happened is the truth. He told me not out of guilt but because I should know and he wanted to know what he should do.   Reddit what else can he do to protect himself but not make the rest of his school year awkward while living there? How should he bring this up to her(hasn't seen her since it happened)? Please reddit gib d advicesss this shit is weird!!!
