Why did Rei take a dangerous space walk to retrieve his music slab during their year-long journey from Tabit to Deucado? I don't know about you but it seems a little irresponsible to me just to get to some music. Rome makes reference to it during their first visit to the Ark II in the novel
The Ark Lords yet Rome does not appear to be too upset about it.
The fact is the incident took place between Parts 1 and 2 of the current version of
Rome's Revolution and was excised during the edit down from the long form to the current version.
The backdrop was they had just escaped the oncoming Stareater and VIRUS consumption of the moon Dara. They were traveling at a lower speed and MINIMCOM figured out how to increase their speed. The entire incident, concluding with Rei retrieving his music slab (kind of a solid-state version of an iPod) will be revealed in the second Intermezzo in the upcoming novel
Rome's Evolution.
