1. Will Jung So Min be a part of part 2?
She'll at least have to make a cameo to show us how Naksu was separated from Bu-Yeon. But I think she'll survive and finally return to Jin clan. Mama Jin is dumb but unstoppable in her search for her lost daughter.
2. Why is Jang Uk using Naksu's sword?
Maybe because he's got the ice stone inside him and to remember Naksu.
3. Who rescued Mu Deok?
I think those were Jin clan's servants. But maybe women from some unknown faction. But I'm betting on the former.
4. How does Go Yoon Jung appear again when her body was burned?
Magical mumbo-jumbo/divine magic.
5. I've a question about who sits on the throne before the entertainers in the preview. Looked a bit like the queen/shaman?
6. Also, with So-i still alive will she be in part 2 and have a redemption arc? Maybe even relationship with Yul? I don't like her personally, I think she's irredeemable.
7. What about Yul and that nasty worm? What will happen to him?
8. Will CP turn to the dark side? Because of his hateful pettiness and jealousy he's directly responisble for Jin Mu's last crazy stunt.
