By telling Canton about Zena and Winnie, Mr. Munch helps Canton realize that he’s not alone. He’s not broken for feeling so much anxiety about his mom, and there are perhaps ways that Canton can get a grip on his fear. Moreover, suggesting a way that Canton can begin to move on from his fear offers hope that Canton, unlike Satchmo, won’t simply let a fear rule his life. So, while Satchmo couldn’t get past seeing dogs as terrible violent beasts, perhaps Canton will have the support he needs to realize buses are more than just weapons, and that his mom is safe.
