Nice conclusion, but i would like to see, that Christy steals Ambers body. so that she has a body of flesh again.
Regarding that... Amber is the leading professor and had already lost her body to Irvin in one of Secret Switches post.Of course Amber has made a new body and have genetically modified it as part of the immortality project.
But what happened to the real Christy?
In regards to Christy... she is likely contained within the Light Cluster Cube, until they negotiate a way to return her body... but this story has a follow up in future once the Zombie Timeline is resolved.
