Observant- Nick named after the philosopher Plato himself; Plato through out the movie makes keen observations about others and from this trait he is able to better help Jim make his adjustment to the new school.
Loyal-Loyalty is one of the main character traits that is shown in the film. Plato displays his loyalty to Jim and Judy by wishing to play house with them in the mansion. He shows them around on a mock realty tour, as though they are interested buyers who are a conventional family. While this displays his need for a family, it also speaks to how loyal he is to Jim and Judy. Plato wishes for them to be a family of sorts, and when Jim and Judy leave Plato to sleep on the ground he asks Jim angrily why they left him. Jim explains that Plato was sleeping and that they'd be coming back later on. Plato acts completely offended, as though Jim were totally abandoning him. His obsession with loyalty stems from his own lack of stability in his home life.
