So AWR is the player being able to keep the Vessel, right? So the question is, then, what happens to Kris? And how am I going to make several parts of the game work, if Kris is no longer our unwilling vessel?
First, Echo is staying with the Dreemurs.
Second, Kris is in the computer lab Dark World, and when the party splits up, Kris and Noelle go together while Echo goes with the Fun Gang. Kris and Echo don't like each other at this point, but they work together on Noelle's behalf.
Third, Kris is Tenna's unwilling co-host in ch 3, and they try to stop the Fun Gang, but Echo convinces them to let the fun Gang go.
Fourth, in the bit in Noelle's house, Kris and Echo have a very Friendly talk in the storage room (the place with the boxes), and Echo tells Kris that they Know and Kris realizes that Echo might be able to save Dess, so they sort of become allies.
Fifth, they show up a bunch in the First and a bit in the Third sanctuaries.
Sixth, Kris in this timeline is less friends with Ralsei and Susie and stuff, and their character arc is mostly around rebelling against the Knight, and working through their grief over the family breaking up / Dess disappearing.
They are a VERY important character, even if they dont have the SOUL.
