What is Paul going to do with his science group after school?

In the novel Tangerine, Paul is partially blind and has been shunted to a new school after a catastrophic sinkhole destroyed parts of his original one. Due to his disability, as well as the abuse he has suffered from his pampered older brother, Paul is something of a loner. He finally makes some friends at Tangerine Middle School through his science class and the soccer team that he manages to get on by lying about his handicap.
The science group comes together in class, and they are going to Luis's house—Luis is another boy at the middle school—after school to work on a paper about a tangerine. It is in this group that Paul finally begins to learn acceptance, and he becomes close with the members of the group and sees a happy and wholesome family at Luis's house.
