Ben 10k timeline. Takes place almost right where the episode "Ken 10" leaves off. (Dark-Gwevin, future AU.) Kevin finds his way back out of the Null Void (again) and tries to take Devlin back. Desperate to keep the child away from his evil father, Gwen makes a deal with Kevin to allow Devlin to stay with the Tennysons. (No one is "good". The kids are the only "not-bad" characters)
