: Now, let's talk nightmare scenarios. You saw how fast a Huragok learned to
: repair the Master Cheif's armor. How fast do Huragok disseminate

: contains unspecified improvements on Covenant technology. How long will it
: be until the specifics of those upgrades spread to the rest of the
: Huragok? What if the Covenant retake the Ascendant Justice, or if the crew

: MJOLNIR armor. Do you really take the risk of letting those secrets fall

: spaceship shielding?
