childhood friend Pete Ross, whom they had tortured and killed. Superman tracks the broadcast radio waves and finds their location. During Ross' funeral, Superman voices his concern that three adversaries who were formerly only nuisances had become murderers, and worries that his more murderous enemies may reappear even worse. While Superman abandons the identity of Clark Kent, Lex Luthor searches an Arctic wasteland for the remains of Brainiac, hoping to study him.
