My mind cannot grasp being buried alive for billions of years and remaining sane. Jones' mental strength is beyond my comprehension. Unless she went to sleep...
I have this worrisome hunch that soon we'll see Jones floating in interstellar space as she has for an unthinkable time, slowly being pulled towards a newly ignited sun surrounded by a protoplanetary disc out of which several planets are forming..
Coyote mentioned stars.
She may be a fallen one.
Perhaps a star's soul.
