I see the Firewalls as key people they have in place to protect the system. No Name was a firewall and if he was truly executed then that makes all the other Firewalls realize this is not a game. No Name might have been the first to actually be executed so that the rest see there is no escape.Will they continue to maintain silence and hope they don't get caught (ie, hold the Firewall to the very end). Or will they realize they are dead men walking.
