Woody’s sister Willa comes to visit the S.S. Tipton, and while Woody is stuck doing homework, Cody offers to show her around. Despite her good looks and seemingly cool personality, Cody soon realizes how similar to Woody Willa really is. Bailey sees Cody and Willa hanging out together, and starts to get jealous so she changes her look to make Cody notice her. Meanwhile, London hires a look-alike, Tess (played by Brenda Song), to do her dirty work, but when Tess sets her eye on Zack, London decides she must get rid of her. Bailey is thrilled when Cody says to Willa that he still hasn't gotten over Bailey. Willa says, "Dang it!" and walks away. Cody thanks Bailey for "playing along" as he didn't get what Bailey was trying to do.
