Was Bernard Strauss responsible for bringing the ten cyborgs on board
He certainly knew of their existence on the Marathon at the time of its launch. His log reads:
"Had he only known that it carried also all of the destructive knowledge of mankind. Ten cyborgs." <Beware of Low-Flying Defense Drones... (Terminal 2)>Leela states in the last terminal:
"I do not believe Durandal himself brought the cyborgs on board, and I have other evidence that a human operator was influencing Durandal up to the time the Marathon was launched." <Ingue Ferroque (Terminal 3)>We know from the log of Bernard Strauss that he was going into stasis for the duration of the voyage:
"I'll be glad to be put in stasis for the next three hundred years." <Beware of Low-Flying Defense Drones... (Terminal 2)>Hence any influence that Strauss had over Durandal would have probably ended after the launch.
Is Bernard (Bernhard) Strauss dead?
Durandal asks you to rescue him on two occasions but after the second attempt he promptly forgets about him. If he was taken on board the Pfhor ship as Durandal believed then he is likely to be in orbit around Lh'owon. His story is yet to be told.
