"Working in a group like this, you will accomplish more, in less time, than you believed possible. You will astonish yourselves."
— A United Mission staffer
Aggie and Lisa spend the summer after sophomore year in Sri Lanka, with a charity mission program that combines camping activities with building homes. Back home, Lisa's parents, socializing with Nick, admit that, much as they love Lisa, the program gives them a break from her constant chatter. Nick, for his part, hopes that the summer will teach Aggie activism through teamwork, not just solitary sign-carrying.
Nick's hopes bear fruit, as Aggie and Lisa not only apply themselves to house-building but also form an unexpected bond with one of the former "Pennies." Katy-Ann, although initially cool to Lisa because of their earlier argument over religion, warms up to her sense of humour as Lisa tells a satirical ghost story about Michael Jackson
. As they work together, Aggie reflects silently on the importance of mutual trust, despite who one's friends are back home. Soon enough, Katy-Ann and Lisa in particular become close as they discover a common love of singing and dancing.
Around the campfire, Aggie tells Katy-Ann she's much more approachable than she'd imagined her to be. Lisa teases her best friend for having pre-judged Katy-Ann, just as Lisa and Aggie had once pre-judged each other. This leads Katy-Ann to open up about Penny and her friends, claiming that they expect perfection from themselves. As a result, she says, they not only fail to recognize their mistakes, but devote themselves to those errors all the more, making Katy-Ann fear for them. This ominous note serves as a segue to the major arc "The Popsicle War," in which Penny and her friends will face an unforeseen, dangerous challenge to themselves as a group and as individuals.
