This week is all about modeling in front of a moving camera -- i.e., how to be a video ho. Or, according to teacher Tyra, a video model. Her master class sees the girls wearing nude leotards, much to the chagrin of retinas everywhere, and she imparts several important lessons to keep you on the correct side of the model/ho line. To wit, when you slide down a wall, your legs should be more or less closed, and when you crawl across the floor, you slide your knees rather than pick them up. It is a line as thin as one fine hair from Tyra"s wig, but we have no choice but to go with it. There are a few recurring themes throughout the episode. The first is that Bianca really likes to talk trash about Heather. Her basic issue is that people baby Heather, and even the judges cut her a lot of slack and hold back on their criticism of her. Like all of Bianca"s verbalizations, it"s stank with a grain of truth. The second theme is that Chantal thinks she"s really, really awesome. I mean, she thinks she"s even awesomer than she previously told us, which is kind of hard to believe. The third theme is that this show has totally given Sarah body image issues. She"s really down on herself, and feels too fat and too thin all at once. The girls get to put all of their new knowledge to use when they partake in a video shoot for Enrique Iglesias"s new single. Lisa gets picked for a little feature bit, to the disappointment of the others. It"s apparently because she"s really tall and has the right look, and has nothing to do with any stripper skills she picked up along the way, because that would be ho-ish. The video"s vampire theme also favors Heather, and so she gets a featured part as well. However, it all proves to be a bit too much for her, and after being on the hot and sweaty shoot all day with no food, she briefly passes out and requires some on-set medical attention. Some oxygen and a banana later, she"s good to go. At panel, Lisa and Heather get kudos for their work, Ambreal is in the middle, much to her delight, and Jenah learns the lesson that she"s not always perfect. However, it"s Chantal and Sarah who are in the final two, with Sarah sent home to deal with her newfound eating disorder on her own.
