Mike informs Mannie that Professor Paz is trying to call his house, so Mannie has Mike cut him in to the call.
Prof says he called to warn Wyoh and Mannie that everyone at the meeting is in danger. Mannie, having already figured out the danger part, invites Prof to their hotel.
The three order breakfast, and Prof updates them on what happened at the rally: The Warden's bodyguards were all killed, and their bodies were, let's say, recycled.
The three decide that the revolution will need a better structure to stay off the radar. Mannie comes up with a covert cell structure that will ensure anyone being caught will not be able to give away the entire organization.
After his brilliant idea, Prof asks Mannie if he'd like to lead the revolution.
