At the next photo shoot, the girls reached new depths as they shot underwater with renowned photographer Russell James. Despite the scuba lessons, some of the girls panicked when they hit the open seas. Laura has a serious fear of drowning, and so freaked out a few times and had to be brought to the surface. She tells Sundai that it really helps if you burp. Sundai wonders how the heck you burp underwater. And speaking of Sundai, she came up with a multitude of excuses to explain why her shoot was such a wash. She has asthma, she swallowed water, her ears hurt. Russell was not impressed, and neither was the panel. Sundai defeated herself with her excuses, and she was sent home. She really wanted to take Roger with her.

After ten weeks in the competition, most of the final four longed for one thing: boys. But not Nicole! A drunken, sunburned Laura says that she doesn't know what Nicole daydreams about if not boys. As Laura says this, there is a photo behind her on the wall that is presumably of her with her boyfriend. He literally has a red neck. Make of that what you will. Nicole replies that she thinks of other things, like bugs and art. Hmm. Erin calls Nicole an anomaly. She interviews that everybody knows things about sex, but somehow Nicole is the only person in the world who doesn't. And then we get a special presentation. It opens up with Laura on the farm saying, "Hi America. Every girl hates to go to their yearly doctor for that special something." I've never characterized a pap smear as a "special something," but okay. Laura puts on a giant plastic glove and continues, "Just be glad you're not a cow." It turns out we're watching "Everything You Always Wanted to Know About Sex (but Were Afraid to Ask Laura)." Laura sticks her hand in a cow's vajayjay and announces, "She's pregnant!" Back in Hawaii, she tells Nicole that sex is like when you mountain bike. You're sweating, and motions and hormones rush through your body, and then you get to the top and yell, "Yes! Yes!" Nicole interviews that the other girls try to talk to her about sex, but it's not something that she's thinking about. Laura tells Nicole that deep down inside we're all animals and want to mate. Nicole asks if they can play hide and seek.
