Wallace is one of the first friends that Martin makes when he leaves behind his old school in Zimbabwe to attend one of the nation’s most prestigious boarding schools. Like Martin, Wallace also comes from a poor area of Zimbabwe, so the two have a lot in common. Wallace manages to get accepted to study at an American university. Though he initially struggles to adapt to the new culture, Caitlin’s family helps him feel more welcome in the new country. Wallace acts as proof, both for Caitlin and for Martin, that it’s possible for someone from Martin’s background to study in the United States, and so his story gives hope to both of them.
