What happens when Gene shoves open the window to Finny's room at the infirmary? How does Finny react? What does Gene say to him?

Gene wants to see how Finny is; he follows Dr. Stanpole's car to the infirmary, and scouts out the room he believes Finny to be in. He waits until everyone is gone from Finny's room, then opens Finny's window and pulls himself inside. Finny is angry at Gene, and falls out of his bed while trying to get up and come at him; Gene says he's sorry, and leaves, walking back depressed.
