The Curtain is Drawn

This is my own idea for the ending of the second season of the last door. It wasn't bad, I could understand it just fine ( unlike most people mainly those from the wiki 🙄).
It was just...really boring for the most part. I'm upset we only got to see the Semurg, the marsh people (the shadows of them) and no other monsters like the Custodian, or whatever the giant bird was guarding. Also, Him. What is Him? It it god? Were they talking about Alexandre, or Jeremiah? Members of the playwright? Couldn't be captain Skidd, we met him.  😒

Alexandre hurried to the curtain in Zha'ilathal, where a masked figure stood. "Jeremiah!" He called and the eyeless masked figure looked at him. "You can't destroy this! Can't destroy us!" Said Alexandre. "Not after all the work we put in to get here!"
He ran down the stairs to the stage where Jeremiah was about to walk in, but thanks to his robe, it was difficult to get far very fast without tripping on it.
Alexandre was soon upon the masked man and wrestled him. "Why Devitt?! Why would you destroy this! Why would you kill all of us?! Erase all of humanity?! This is not the answer!" Shouted Alexandre.
"We tampered with things we shouldn't have! We opened that we should not have and let it in! The Hoopoe could not protect us no matter what!" Shouted Jeremiah. "Not after what we'd seen!"
"But you can't undo all this! What about the pact we made with Anthony! What about what happened to Hugo?! We can't let him just ...look, we can't just toss this away, not after everything we did to get here!"  "Hugo never would have...if we hadn't...!" Jeremiah shouted and wrestled Alexandre off, and went to go inside. "Jeremiah!" He shouted. He scrambled to his feet. "Jeremiah, no! You can't..."
Alexandre soon used a memory and wrapped it in shadow, before sending it to Jeremiah, who suddenly froze and looked slowly back at the man. Alexandre just looked at his old friend as he looked down at his hand that had begun to transform and he took the shape of an monster, a deformed spider like creature that roared in agony and ran out of the Threshold. Alexandre breathed a sigh of relief, glad to have not been torn to bits, but looked sadly at the eyeless mask that his friend once had. "I'm sorry...Jeremiah..."
Alexandre heard a scream coming from somewhere, but not within Zha'ilathal. "What was that?!" He shouted and he ran to a mirror to see the puddle in Adam's old tunnel and saw a man in blue clothes running for his life. "Dr. Wakefield...wait...oh no!" Shouted Alexandre as Jeremiah chased him, begging for forgiveness.
He watched the scene unfold until he heard Wakefield fall down through the large hole, where the sea carried him away out of the caves and out into the open.
"Oh no...." Said Alexandre. But he heard a splashing noise and looked in another mirror to see Wakefield having grabbed onto a large driftwood and held on as it carried him back to shore, unconscious, but Alexandre could tell he was alive. "Thank heavens...although, this still presents a problem."
He looked at the entrance to the Threshold. "If an outsider ends up here then they could undo all our hard work as well..."
He looked back at Wakefield, drifting on the sea. "This...gives me an idea..."

So Alexandre had set up a fake Jeremiah Devitt, using the being of smoke and shadows known as Kohff.
"Okay, you need to meet this John Wakefield guy at the dunes at the entrance to the Veil and guide him here. Once that happens, you need to trick him and make him take Jeremiah's place." Said Alexandre. Kohff nodded, his eyeless gaze behind his mask unyielding. He left, disappearing in a thin wisp of smoke to the entrance, to wait. Alexandre kept tabs on Wakefield, before the doctor seemingly disappeared.

Wakefield had wound up in the Veil, during his trip to Éilis Mór, when he entered the tunnel into the crypt, and the villagers had sealed him inside, trapping him forever.

He walked through the fog, passed the Marsh Dwellers, who had stolen Kieran and turned him into a hideous form and passed the many eyes that looked upon him, their gaze unyielding before he walked up to what he knew could only be his patient, Jeremiah Devitt.
"Mr. Devitt?" Asked Wakefield.
Jeremiah turned to look at him, as if surprised, before he immediately relaxed and looked at the doctor. Wakefield of course, had many questions. "Where did you go? What happened? Where are we?"
But instead of answering, Jeremiah went to walk through the dunes away from the beach and gestured for Wakefield to follow. He felt uncertain, but didn't really have any other choices, so he followed his patient through the dunes.
