In a separate peace, in chapter 8 what two psychological events for finny take place in the gym setting?

Gene and Finny keep training, doing long runs in the morning; Gene thinks he can't do them, until one morning he just amazes himself and it comes naturally to him, just as it did with Finny before. Mr. Ludsbury, one of the teachers, discovers them at their morning exercise; he tells them to keep it up as some kind of preparation for the war, and Finny just blows up at him, telling him it has nothing to do with that. Mr. Ludsbury turns red, gets angry, and stomps off; Finny has no remorse for angering the man, though Gene feels somewhat strange about what happened.
