Dr. Auburn-Stache is at Oliver's house for his weekly check-up. Oliver has to have the doctor come to his house because he cannot leave his house since he is allergic to electricity. He has to live far in the woods.
Liz is Oliver's friend who comes to visit him. She lives a couple of miles away. They were bestfriends until school started and she didnt come over anymore.
Oliver met a friend named Moritz through writing letters back and forth. Moritz is blind and school is very hard for him.
Moritz is very smart and uses his ears and his nose to know who is around him and where is he is. He is bullied by a lot of people by getting slammed into lockers or punched.
Moritz can't meet Ollie because Moritz has a pacemaker so he can breathe. If he shuts it off, he will die. If Ollie is around Moritz's pacemaker, Ollie will die.
