SUPERB. Just like:
Episode 8, 9, 10 and 19. This is EVIL DEAD, guys. This is the spirit. Groovy!
I loved every bit of this episode. Every second. Terrific direction. Terrific visuals. Ash looked and sounded very serious, he reminded me of "the" Ash of EVIL DEAD II. There was some drama from his part, sure as hell.
Just a little premise:
Episode 19 just showed us that Ash has "reminiscences" from previous continuities/iterations of the alterable Evil Dead timeline. This pretty much validates my Plastic Universe Theory. Just rewatch the sequence in which he has two juxtaposing memories about "where he originally found the Book of the Dead, 30 years ago". Just brilliant.
So basically, this is my step-by-step analysis of Episode 20:
1- The fight with Evil Henrietta was gory, scary, "delicious" and very ARMY-like, all rolled into one. This is one of the biggest and most thrilling moments in the whole TV series. In the original timeline, Tanya was meant to die anyway, so that's not a big of deal. She was "already dead", sorry.
Her bloody face reminded me of Mia. Astonishing.
2- The escape from the Knowby Cabin reminded me of EVIL DEAD II. Pablo was Baal. The new hand growing from nothing was just some kind of "quantic resonance" playing out in the ALTERED TIMELINE. It was a nice nod to many time travel movies featuring REVISABLE timelines. The new hand was genuine, and not Baal using his demon powers to fool Ash. As simple as that, there was a kind of mystical connection between Old Ash and Young Ash at that point, and the hand just regenerated from nothing.
Later, the hand being possessed was a "solid illusion" created by Baal. The Kandarian Demon wasn't there anymore.
3- Chet and Bad Cheryl were just "solid illusions" created by Baal.
I'm not entirely sure about Brock... but maybe even Brock was an illusion created by Baal. The chainsaw wasn't an illusion, and perhaps Real Brock truly helped Ash.
Don't forget that the second chainsaw (the one Baal was manning) was the UNALTERED Evil Dead II chainsaw previously stored in the toolshed.
Or maybe, Baal wanted Ash to fight and "Brock" and the chainsaw were just "staged" by him and his demon powers.
And yes, there was a BIG HINT to the secret of Episode 13... "me and you"... "the reality"... hey, this is meant to be solved in the next seasons! Relax. Don't hurry up.
4- The DEAL was not "altered" by Ruby. It was "respected", wherever Baal wanted to cheat. Ruby made Baal "mortal" for real, despite keeping his demon powers intact. It was a smart move.
5- Pablo is saved. And well, he has no "Book powers" anymore. So they cannot come back home (2016), which brings us to the last point...
6- THE PARADE is an illusion created by Ruby. You can see the "dream-like slow motion" sometimes. The colors are unnatural. The cinematography is also "dream-like". Even Ash is questioning the reality at the very end, noticing it seemed too "perfect". LMAO. It was evident. It felt very "Dexter Season One Finale".
My theory. There's one timeline. They altered it. But they are still stuck in 1982, and Ruby fabricated this "Alternate Elk Groke Reality" to keep the heroes caged in some way. It's a mental reality. They are physically trapped somewhere in 1982.
Or:
They travelled to an Alternate 1982 (parallel universe).
They changed the timeline of THAT specific Evil Dead universe, not theirs.
LISTEN RUBY'S SPEECH WHEN THEY MATERIALIZED IN 1982, EPISODE 19.
Hope this post will help you. Have a nice bloody day.
