At first, I wasn't sure if Jimmy was being sincere or if he was acting, but it turns out he was acting. Kim seemed so happy for Jimmy during his speech to the panel, but that all was taken away as soon as Jimmy said "I fooled them all."
I liked that scene with the student. Jimmy is the type that he wants to give a person a second chance and roots for that person to do well, as that was him throughout his life. When he tries to do the right thing and it doesn't work out, he gets easily discouraged and reverts back to Slippin' Jimmy.
