How does repackaged Marcy remembers the collapse of shelter 41
027/Grace stated in epi 11 that she had to work with the material available to her, which was Marcy in her future condition, prior to being sent back.
Grace states she did not have access to Marcy's memories of the 21st century. This implies that the information she used was future Marcy prior to being sent back in Grace's future.
Grace herself comes from a future with the faction and where shelter 41 did not collapse. Repackaged Marcy should originate from this future as well. But repackaged Marcy in epi 12 remembers the collapse.
How can this seeming contradiction be explained?
