chunk: Nolan investigates Neil's death at the request of the Perry family. Richard blames Neil's death on Keating to escape punishment for his own participation in the Dead Poets Society, and names the other members. Confronted by Charlie, Richard urges the rest of them to let Keating take the fall. Charlie punches Richard and is expelled. Each of the boys is called to Nolan's office to sign a letter attesting to the truth of Richard's allegations, even though they know they are false. When Todd's turn comes, he is reluctant to sign, but does so after seeing that the others have complied.
