The father of Cody, brother of Dock and Stew, and uncle of Sophie and Brian, Mo begins The Wanderer having a poor relationship with his son. Constantly yelling at and scolding Cody, Mo has practically given up on trying to reach out and forge a better, healthier relationship with his son. Mo also is characterized from the start of the novel as lazy and out of shape—preferring to watch everyone else work while he sits back and pretends to be in charge. While Mo’s laziness doesn’t really change throughout the novel, his relationship with Cody does. After the crewmembers of The Wanderer have a run-in with a nearly fatal wave, Mo comes to appreciate the fragility of life more, and tells Cody that he has been a bad father. The two begin to repair their relationship, and mend the wounds they had at the beginning of the novel. Mo is also a talented artist, and, though he may not be the most helpful shipmate, he draws pictures for everyone aboard The Wanderer and gives them out as gifts in England.
