These are Wild Mass Guesses regarding the Cabin Fever films.
- Paul comments that his "accidental" intrusion on Jeff and Marcy was actually the second time he'd burst in on them about to have sex. Once may be bad timing, but twice? He was hoping to catch a peek at Marcy's boobs.
- He'd just been on a long car trip with them, watching the sex crazy pair do everything short of undress each other in the car. So when they arrived at the cabin and Jeff and Marcy go in to the bedroom and close the door behind them, what did he think they were doing?
- When the group have a discussion about halfway through the movie and Marcy gets up and leaves, Paul's eyes seem to be watching her butt as she walks away.
- When Jeff starts acting like a wuss after Karen gets sick, and Marcy starts getting frustrated with him, Paul suddenly has an angry outburst where he tries to act all leader-ly. He's showing a little alph-male aggression to impress Marcy, now that he thinks she's not so attached to Jeff.
- In his speech, he suggests that they "eat alone, sleep alone", to prevent spreading the disease. Marcy seems to agree with his advice and doesn't share a bed with Jeff that night... She shares a bed with Paul instead. Paul isn't shown talking her in to his bed, but at the very least, he obviously didn't object to her going against his own suggestion. And if it was just a case of him being chivalrous, he could've given her the bed and slept on the couch, but instead he chose to share it with her.
- Paul barely leaves Marcy's side the whole of the final morning. Every important act they do in this timeframe they're shown doing together.
- When Jeff finally decides to abandon everyone, Marcy goes chasing after him and Paul tells her to just let him go. He doesn't seem the least bit interested in persuading Jeff to stay with the rest of them. In no way does it make sense in an emergency situation to let a group member run away and isolate themselves from the main group. On the other hand, if you want to be the rebound guy, you'd be more then happy to see the girl's ex disappear over the horizon.
- After Burt and Jeff leave, Marcy and Paul put Karen back in the dark toolshed. They must get seperated briefly, then Paul is shown looking for Marcy so he can sit with her can comfort her. Yes, that's right. Karen, the supposed love of his life, is dying all alone in a dark tool shed, after just vomiting a bucketfull of blood all over the pickup truck, and it's perfectly healthy Marcy that he wanders off to comfort. Yeah, because she's the one whose really having a bad day.
- In the fullscreen version of the movie, you can see that when he sits on the bed beside her, Paul places his hand on Marcy's thigh. Like, really high up her thigh, getting outside the areas where "just friends" would touch each other.
- Their sudden sex scene makes a lot more sense if you considder that Paul always wanted to do her, and Marcy secretly knew. Then suddenly it's not like she's just randomly decided to have sex and grabbed the nearest guy available. She figures she's got no time left so there's no point rejecting him anymore. She might as well go out doing something they'll both enjoy.
- Also explains why she seems so shocked immediately afterwards when Paul decides to leave the cabin to go look for Jeff
- While initially he's understandably a bit reluctant about doing a babe who might have a fatal disease, it doesn't take Paul long to bring a truckload of enthusiasm to the deed. It's almost like he's living out his dream.
- Look at her. Karen's nice, maybe a 7 or 8 out of 10. Marcy's an 11.
- Also, they may have done it twice even on camera. The sex scene we see is broken up in the middle by a shot of Karen dying in the tool shed before it cuts back to Paul & Marcy doing the mattress mambo from a different angle. Most people would just assume that this is the same sex we'd just seen finishing up. But in the earlier shots, they were near the edge of the bed whereas in this shot, they're in the middle. Also, the way Marcy was pinning Paul's arms down in the previous shots would've made it impossible for him to be able to reach up and grab her back to make the wounds we see later. But most telling is the fact that Paul wasn't wearing his watch in the first part, whereas in the second, he is. Guys don't put on their watches while there's a pair of D-cups jiggling 3 inches from their face! So perhaps, the first part was one sex scene. They finished, got out of bed, started to get dressed, Paul put on his watch. Then one or both of them got another craving and they climbed back into the ring for another round. So the other "the night before" theory is correct too, Marcy might've given Paul 3 wild rides. Go Paul!
Consider also the following:
- She didn't use a condom. Despite often being regarded as careless renegades, promiscuous people are usually very careful and tend to keep precautions on-hand. Especially women, who run the risk of getting pregnant. Marcy certainly seems like an intelligent woman.
- If she thought she was healthy, the possibility of Paul infecting her would've concerned her just as much as he was.
- Many people have noted just how out of place that entire sex scene seems in the story, if taken at face value.
- Marcy was incredibly aggressive in that encounter - firmly holding Paul down on the bed as if to prevent him from escaping.
- Her quick response to Paul's question about condom's: "Don't worry. I'm healthy." Despite the incredibly flawed logic of the statement, she quickly puts the matter to rest. The question didn't even make her hesitate to reconsider the dangerous thing they were doing. It's as if her only thought was to shoot down Paul's urge to put on a condom.
- The fact that she went straight to the bedroom after they put Karen back in the tool shed. It could be an innocent move, but on the other hand, it could've been that she was just laying in wait for her prey to come to her. As the last "healthy" person in the cabin, she would've known that Paul would quickly seek her out.
- She brings up sex after all of 30 seconds of conversation with him. Seriously, how quickly would someone sober decide to get it on with their ex's best friend? She probably decided to have sex with him long before he actually entered the room.
- She'd undone her hair. Most guys think a woman looks sexier with her hair down than with it tied back. Did she do it to be more seductive to him?
- Any grabbing that leaves welts that are still sore ten minutes after the fact has got to be painful while it's happening. So why doesn't Marcy rein Paul in if he's hurting her while they're screwing? It's almost as if she's not doing him for pleasure, but putting up with it for some ulterior motive?
So why would she deliberately try to get him sick, too? Well, if she's convinced she was gonna die, then she probably didn't want to die alone. Jeff and But had just run off and Karen was already at death's door. She probably figured that Paul would probably run off sooner or later, too, leaving her all alone to die of the illness already killing her. But if he was sick, too, there'd be no point in him fleeing. He might as well just stay and die with her. Notice how surprised and upset she gets later when Paul decides to leave the cabin to look for Jeff.
Jeff - Law (He threatens to sue the redneck store clerk when Paul gets bitten by Dennis)
Bert - Auto Mechanics (He's the one they task with fixing the car after the fight with the hermit.)
Marcy - Nursing/Medicine (When Paul discovers Karen is infected in the fingering scene, she's the one he calls for.)
Karen - Photography? (Umm, carries a camera in the beginning and takes pictures)
Paul - How to get away with murder? (He shows to be a very proficient killer towards the end. He kills Karen, The Dog, The Redneck Gang, almost kills Winston)
