During his Sunday sermon, Eric proposes that instead of a financial contribution, everyone should make a commitment to reach out and help someone in need. Kevin suggests that he and Lucy work together to set up a neighborhood watch program, but she feels passionate about working with Habitat for Humanity. Eric calls his new son-in-law Carlos (guest-star Carlos Ponce) and asks him to fly in without Mary for dinner with the family, which makes Carlos very nervous. Also, Ruthie picks a shy new girl at school as her project and soon finds out that she has a secret. Meanwhile, Peter picks Ruthie as his project, which prompts her to tell him that they should spend less time together. Chandler and Roxanne keep running into each other stirring up old feelings. Lastly, Annie becomes jealous of all of the time the twins are spending with Cecilia.
