Hi looks like a rival to Gene but deep inside he is a good person. He is the best athlete. He isnt very bright but he is bright enough. Finny accepts Gene as his best friend and does not get mad at anything that Gene does. He is a boy who rivals everyone.
Gene takes everything in a bad way.
For example Finny says'I tried to catch you'. Him suspecting everyone puts him in the shoes of a crazy boy. He is very clever and good academically. He is the best athlete. He isnt very bright but he is bright enough.
