I think it would be neat for Julie to get a glimpse of Shepard as she is undergoing the ascension ritual! Aloy and a native Abraxan is there— a thin, blond woman who will eat the offering, and die very soon after the end of the ritual. Julie would be able to see Aloy going through it, and also Shepard's own vision of the ritual from her perspective. The thread will be here as it gets going.
