Yea, the real queen is still alive in the shaman's body somewhere. It's not known about the shaman's sibling in Jinyowon, maybe the sibling got trapped in an artifact or smth.

Naksu.

Judging by the preview he'll spill the beans to Park Jin about her finally and they'll try to separate them to protect Uk. So I think considering everything else shown there she'll be exposed.

Nothing is clear when it comes to FL's body, she's the biggest mystery of this show!

But they already know that Naksu was Cho mage's daughter. I recall it was mentioned by them already? So they can't say it is Mu-Deok. But exposed Naksu in Mu-Deok's body is another matter and that way she can pay respects to her parents in the preview scene.
Also, there was a scene in the preview where master Lee tells maidservant Kim that there is a Cho soul in the house, lingering by Uk?

Also a good guess. But does the pool show the body's or the soul's constellation?
Also, if they'll think she's Jin daughter what's up with that paying respects to the dead scene? Would fit if they were Naksu's parents, but Jin daughter's parents are both alive.
And the scene where master Lee tells maidservant Kim that there is a Cho soul in the house?

So, guys, your predictions for the next episodes?
-Judging by the preview I'm thinking Naksu will be exposed finally, but won't be punished. Park Jin already knows everything about her and he's strict, but maybe master Lee will step in. And judging by the preview Yul will be the one to spill the beans to Park Jin about her finally and they'll try to separate them to protect Uk.
-The villain Jin Mu's actions should be exposed as well since Uk and Mu-Deok will get out alive from Cheonbugwan. But he'll wiggle out of it and enact his fake Jin daughter plan to fool and soul shift poor dumb Jin mother.
-CP will get even more jealous, will up the bet to Mu-Deok herself and will set Yul to fight Uk as the last combatant. But Uk being a genius will have learnt all the other combatants spells and will win the fight for the precious egg and Mu-Deok.
-More annoyingly inevitable love triangle scenes...

Me neither, but backstories are important to understand the villains actions and flesh them out more.

So does Jin Mu. He was hated in Jin clan for being born out of wedlock, and he had a tough and hungry childhood. He wants power and revenge as well.

This show is unbearable, after trying for a week to finish watching episode 7 I'm giving up. This drama is a ridiculous circus show with a boneheaded, insufferable FL and childish clown for ML. I'm also starting to guess why it's 18 episodes long - leads are so dumb and uncooperative they will be trying to catch the villain many times and losing him until the very end.

I've long been wondering about those stone statues swimming in the lake. What if they all can be brought back to life?

Yea

The body was dead but the soul alive? Or the body was ok but had no soul? So far it's unclear, but if it's like with the almost dead guy then she had a soul.

Keep in mind that scenes about this span several episodes though, if you want to check them out.

Maybe that space where souls reside is not constricted by bodies. Maybe it's like all-permeating ether.

Pay attention to all past scenes of 200 years old and when evil guys Jin Mu and the queen are talking among themselves. The queen got soul shifted, now her body inhabits an evil Choi shaman with a grudge towards Songrim. Mage that was shown holding the shifting Ice Stone and getting black powder for soul ejectors in the past was a Choi mage.

Mu-Deok's soul is in her own body along with Naksu's. Have you not seen her sleepwalking or using her powers thrice now (mirror, saving Uk, saving herself) when they're needed?

Yea, they be like: 🔷✨💖😱🤮😱💖✨🔶

They are a disgraced clan from past times with a grudge towards Songrim and its founder for exposing their misdeeds. They want to destroy Songrim.

With the way more and more love triangle characters get introduced it is indeed similar to Marvel movies where new heroes are introduced frequently. Let's hope this show won't end on a extra scene cliffhanger like all Marvel movies tend to. Let's hope there is finality to AoS story as well.
