I will wait for more episodes in order to revise my continuity scenario.
1- "Ash vs. Evil Dead" is an alternate continuity. Okay.
2- "Ash vs. Evil Dead" is a sequel. Okay.
Let's wait for more to come from Ruby Knowby and the Book itself...
For the rest:
THE SHOW IS A TRIUMPH!!!!! This is EVIL DEAD. Pure and uncontaminated Evil Dead madness.
