Gene realizes that if he were in Finny's place, and Finny was responsible for the accident, that Finny would confess the truth; but Gene realizes he doesn't have the strength and nobility in his nature that Finny has, and this upsets him very much. Gene gets ready to tell Finny the truth, however much he doesn't want to. But, he doesn't get the chance to speak, as the doctor comes back in; and, before he can see Finny again, Finny is sent home to recuperate.
