I wish they kept that line in the film.
I always imagined Jenny got together with Fixer and Camie, and they had their own adventures that were almost but not quite remembered by the Galaxy at large. Some historians claim their adventures were recorded in “The Book of Jenny”, but prevailing consensus now believes these were apocryphal additions to the Journal of the Whills, known only through later accounts falsely attributed to Mace Windy and C.J. Thorpe. Other evidence may suggest these accounts were lost when the Journal of the Whills was recompiled by a later scribe known only as “Marcia L.” as attested in the margin notes.
