Okay. This is what I think.
RG, interested in Ak, went to Le Chic to "run into her." PL tells him that AK is scheduled to work, but he was giving her the night off because it was so slow around there. In discussing the girls at the cottage, PL and RG agree that MK is attractive, too, and PL says the girls both have BF's already. They joke that the BF's are no match for them in terms of romance. PL texts AK that she has the night off.
AK gets the text, talks to RS's friend, turns off her phone because she left her charger at home and doesn't expect calls since RS is with her. RS downloads another movie, but AK is tired of movies. she thinks she should go home to get the mop since the pipe burst. He doesn't want her to walk because it's dark with the time change, so they set off.
PL decides that since it's dead at the bar, he's gonna go to the cottage to talk to MK about her bartending job. RG tags along. Meanwhile, MK arrives home and sees the two men on the rail at the street. They hop over it, so they don't have to walk by the cameras, and PL talks to MK on the porch about her new job as she unlocks the door. PL's phone pings in the area.
AK and RS arrive to get the mop about 920pm, while RS is in the bathroom. After a brief conversation with MK, AK, and RS, PL heads back to Le Chic.
RG comes out of the bathroom and MK seems to act awkwardly as he is making himself at homme. RS and AK say nothing, assuming that RG was there because MK wanted him there. They leave out with the mop and bucket to put it in the car.
MK tries to tell RG that it's time for him to go, too, but thinking they were alone, RG makes advances on her and a fight ensues.
In the car, AK thinks it's weird as hell that RG was there. They drive up the road, but AK is not comfortable. RS says maybe they ought to go back there. When they get back there, AK screams to see MK dead on the floor. RS removed his shoes and went into the MK's room to roll her over and check her vitals, somehow touching something that touches the bra clasp. Seeing she's dead, he puts the duvet over her and closes her door. He got blood on his bare foot, so he rinses it in the bidet.
AK has completely fallen apart and she's hysterical and RS doesnt know what to do, so he just takes her back to his house. He wants to call the police, but RG comes to the door and threatens them through the door speaker thing. AK grabs the knife in the drawer because she's scared, but the tip of it bumps into RS's shirt, which as MK's dna on it from when he checked her vitals. RS convinces her to put the knife back in the drawer because the stranger at the door can't get to them.
AK wont let RS call the police after that because she's scared out her mind. The next day, RS convinces her that they have to deal with it, so they go to the cottage, and AK freaks out to find the window broken, the crap in the toilet and MK's door locked (Apparently RG returned to the place).
They call police. RS has no idea who RG was anyways, but RS is surprised when AK doesn't reveal that they'd been there the night before. He goes along with whatever AK is conveying to the police. PL meets with AK to make sure she wasn't telling them that he did it just because she saw him there earlier. In the interrogation on the 5th, AK breaks down and only remembers seeing patrick that night, because she was all confused and couldn't even remember RG's face, just his skin color. meanwhile, they take RS's shoes and try to pin the footprints on him, and he tells them AK's story was crap, but he's so scared, he says he wasn't even with her for some time that night, and well....you know the rest....
Oh, and all the other evidence is just as unexplained as it has always been.
