Plot hole: After Chucky electrocutes the psychiatrist at the hospital with Andy there witnessing it, all of a sudden Andy is at home on his own barricading himself in then hiding out waiting for Chucky to turn up. How did Andy get from the hospital to his home considering no adults were with him? (01:07:00 - 01:08:40)
Plot hole: Andy is suspected of having killed Eddie Caputo, because he was at the scene when Eddie's house blew up and Eddie was killed. But there are glaring things that go unquestioned: None of the cops seem to think it's strange that a six-year-old kid would travel by himself so far to some random house in order to blow it up. The South Side neighborhood where Eddie lives is halfway across the city from Andy's apartment. How did Andy know where Eddie lived? How do the cops think he even knew Eddie at all? None of them address this most puzzling problem.
