Carman=Cardenas and their sons
Including a theory about Wakti Wapnasi, Amanda and the Mage
(EVERYTHING IS CONNECTED)
The update version of my theory, after having watched "Shapes and Colors" is the following;
The Cardenas had two children. Arnold Cardenas and his brother who is Moloch.
The two brothers used to love playing cowboys. Then one day a boat fell from the sky and Arnold found a creature in it, Wakti Wapnasi. He brought her home and she gave him presents. Like the air gun and the house within the house, including the purple people eater.
I think that the house within the house was one of the first ones. Then the gun and the purple people eater. Everything spiraled out of control.
At first it was all fun and games. Arnold had the air gun, both of the brothers dressed up as cowboys. He pointed it at his brother as we can see on the pictures on the wall.
He pulled the trigger, not knowing that it was actually dangerous and hurt his brother. Bad. He fell into the coma that he is still in (or used to be, who knows what Amanda is capable of?).
The boys were separated. The Cardenas put their unconscious son into the room with the cowboy stuff:
And Arnold into the room without windows and just a bed. Punishment. They didn't want him to hurt his brother again.
Little Arnold, left alone with nothing but his imagination, a pack of crayons and a TV (showing knights) created Wendimoor, not knowing that it would become real. It was the thing that saved him from the real world, just like Dirk had that fantasy about Todd and Farah saving him and starting a real detective agency.
Then the flying purple people eater escaped (or he did before all of this happened, idk.)
The government noticed the Cardenas' and their sons, or well, the purple people eater. Priest arrived later to find the psychic responsible for this monster. Then he killed their parents (notice the broken fingers on Mr. Cardenas' hand? He did the same thing to Vogel).
Arnold managed to escape just in time into the house within the house. Priest found Moloch and probably came to the same conclusion as we did at first: Everything of these things came from a child's imagination. And Moloch was the only child he could find so he took him with him to Blackwing. Mission Diamond. (Or whatever it was called.)
After a few hours or even days, Arnold crawled out of his hiding spot. He found his brother missing and his parents dead. He didn't know what to do and was scared because he thought that all of this was his fault.
So he asked Wakti to help him one last time and she let the trees grow around the corpses. After all, she's a forest witch. Then, as he said, he took care of it. It wasn't human. He ended it.
Arnold killed Wakti (or that's what he thought he did) and put barricades in front of the entrance to the house within the house. He left everything behind, even his own name.
But Wakti wasn't dead. She managed to survive and wants her revenge. Maybe she needs a child's fantasy or something like that (Moloch-child sacrifice) and now that Arnold is gone, she's connected to Moloch, living from his energy. Or maybe she only survived because she escaped into Wendimoor, the last piece of a child's imagination left after Arnold was gone. But I think that there's definitely a connection between her and Moloch.
The point is: She's the villain from the prophecy and Amanda is her apprentice. Wakti wants to cross over into the real world and "Find the boy" (Arnold?) and get her revenge (or lunch?) But her child is in a coma and that's why she isn't strong enough, she needs Amanda.
Everyone is just a puppet for her. The Mage for example. She probably told him that he will be rewarded (parallel to Dirk telling Todd that the universe will reward him and we know how that ended) but then he saw the prophecy. "This isn't how it was supposed to be."
He helped Wakti to forge a fire between the Trosts and the Dengdamors so that she could be the good one. She that knows Amanda would never help her if she knew that she's the villain.
I think that Mona was Wakti's first try on finding her apprentice. Mona, the easily to manipulate and unloved child. Wakti gave her love (just like she does it with Amanda now) and Mona played after her rules. Still does, kind of. But Mona wasn't strong enough. Amanda is.
Lamia can't close her eyes. I think that when she has green eyes (just like Wakti), it's Wakti seeing through her eyes.
And remember the part in Amanda's vision where something crawled out of the bathtub? Panic Pete (aka. Mona) next to it on the toilet, with glowing eyes just like it had them after Wakti pulled it out of the water? And the hand coming out of the bathtub, grabbing the edge of it looks like Wakti's. Plus the photo on Max' Instagram of that green eye and wrinkled skin. I don't have photos of it at the moment, I'll add it if I find them again. Or maybe you guys have these? I think the thing in the bathtub is Wakti and Amanda helped her reach the other side, thinking she's doing a good thing.
And @ the Amanda is her apprentice thing: We know that Amanda is going to turn into a giant snail at some point in this season (like Wakti?) and that she has to wear a heavy special hat. Maybe also the same one as Wakti is wearing?
Oh, and with Moloch being in a coma and Arnold trapped in the room without any windows, it would explain why there wasn't anything about children in the files.
Well... That was my theory but I probably forgot something else than just the pictures. Anyway. Let me know what you think :)
