By day, Jill shoots Brooke's new line of Von Weber wares, and by night she and Vanessa investigate a rash of infections plaguing the Upper "Yeast" Side. Candace seeks answers for why she keeps getting called "Candy Ass," and Lex tries to make the cut at MarsX. 

At the annual family sleepover night at The Brewton Museum of Natural History, animal instinct takes over: Brooke has cold feet about Lex going to Mars, Simone reveals her unexpected true love, Vanessa surprises herself and Andy realizes he's been chasing the wrong girl all year.
