Oliver has no one with whom he can share his secret, so he summons Alexander Graham Bell. However, his secret is uncovered by a curious 14-year-old named Dee Sampson who, thanks to Bell’s advice, Oliver eventually befriends.

Dee is upset by her parents’ investment in a toxic pulp mill, so she summons Joan of Arc to help organize a protest, despite Oliver’s reservations.
