Your wildest theories on AoS (part 2) - THANK YOU ALL

I gotta say it's either a big retcon or a confirmation that genetics pass down through biology, not souls.
Mama Jin believed that since Bu-Yeon's blood still courses in Naksu's body, Naksu can birth an heir with priestess powers. This contradicts what Jang Kang and late King believed in - they believed genetics pass down through souls.
My guess is nobody actually knows shit and believes in whatever nonsense they want since it's basically medieval fantasy times with no science whatsoever. And mama Jin is a dumb delulu bitch. 

And I guess that's it for Bu-Yeon - a sad end. Her soul is dead, her body converted to take shape of Naksu's soul. But good for Naksu I guess, she's back in her body and no longer a soul shifer. She just needs to regain her memories.

And mama Jin got nothing in the end, she's stuck in limbo now, the only thing left of Bu-Yeon is the blood still coursing through what is now Naksu's body. I'm good with that, she didn't deserve to have Bu-Yeon back. And I hope she gets locked up herself in the end, because she's just crazy.

If I understood this correctly, no memory equal no power. When Naksu regain her memory she will also have the power of Jin Bu-Yeon? Two soul becomes one.

I don't think this will be a happy ending.  In the first EP Yul said its ongoing drought in the lake and the energy is weak. In the ice stone  JBY tells Mu-Deok she will gain some and lose the other. Since Uk have The Ice Stone the energy in Daeho is reduce. Someway somehow Uk(he wants to remove the ice stone anyway) will sacrifice himself to bring everything back to normal. 

Here is my simple theory on how Naksu could possibly gain her memories back, not sure if someone mentioned this before: 

Jin mu knows that Bu-yeon is Naksu, therefore will he try to use the bell on Naksu again to wreck havoc. If he does my theory is that Naksu will regain her memories when he uses this bell, not sure if it would be all her memories or just the ones when she went on a killing streak.

Ok but I just remembered that Park Jin literally fought face to face with Naksu. That means that he might recognise her. On the other hand it's been over 3-4 years since they fought each other so he might have forgotter what her face looks like. Still he could be like "Oh wait I think I've seen her somewhere before".

I have a question about ice stone.

We learned in part 1, that many people fought for ice stone since many years ago until The King's star Master Seo got rid off them and only one of ice stone was left, he saved for Jin Seolran.

We learned about only great and powerful things about it. No one gets informed that this sufferings and price you have to pay as ice stone owner?

Before Uk got ice stone, shaman choi was the one who owned it. She seemed fine at using it too. 

Now, The King's star Uk become ice stone owner, he is suffering with those wraiths wandering around, being soul-shifters' target...

Uk said it's too much for him to handle. Isn't Uk the King's star who is supposed to destroy it? Why is it too much for him? Am I missing something?

3. Guesses about Seo Yul's sickness?

Maybe the worm with Jin's blood that So-Yi had planted in him in an effort to save him or something psychologically related to missing out on first love yet again(The trauma trope)

After watching S2E4, I'm a bit tired of the princessy innocent Bu-yeon and ready for badass Naksu to appear. I loved the chemistry between Uk and Mu-deok in S1 in part because of Mu-deok's courage and bravery and zestiness. I wish Master Lee (who should have told Uk about Naksu/Bu-yeon) could multiply Naksu into three people: a Naksu body for Seo Yul, a Mu-deok body for Uk, and a third version for the Prince. I want Yul to be happy, too! (And not with that pickpocket mess of a girl.)

That said, the ending of S2E4 was very sweet and I might have teared up a little.
