Highly unlikely since if she's locked or trapped somewhere the bird would most likely not be able to enter and…
My assumption is that if they're locking up Mu Doek/Naksu for good, there'd be magic involved so the bird wouldn't be able to get there. But let's see...you never know!
From hints being dropped I feel like we'll get a show down of Mu Deok/Naksu vs Park Jin again once it's revealed to everyone that Mu Deok is Naksu. Or rather it'll be Jang Uk and Mu Deok/Naksu vs Park Jin showdown. Looks like our leads are going to have to fight it out with Park Jin and other members of the leading families before their final battle with the villains!
So I was watching episode 4 again and at the beginning they're talking about how the King's star only appears/reveals itself when the sky is filled with the energy of the Daeho waters. So that's means Jang Uk's energy is in fact as powerful as Lake Gyeongcheondaeho - and as Mu Deok/Naksu said, she believes only someone as strong as that can help bring back her energy - Mu Deok/Naksu predicted that correctly . It'll be interesting to see just how Jang Uk brings back Mu Deok/Naksu's powers. I wonder if the yin yang jade will play another role here. The show has gone to lengths to show just how important that jade is. Not only the sentimental value but also the power it carries.
Master Lee is just above the Chisu level and Jang Uk has already mastered that. I'm guessing we'll see Mu Deok/Naksu getting her powers back in the next 3-4 episodes.
So in the article that's going around, it also states that JSM had initially signed on for both parts 1 and 2 of AoS.
If there's some truth to that article then that means that both JSM and GYJ will bee seen in part 2 of AoS. It makes sense, I don't think they'll kill off My Doek/By Yeon that easily and of course Naksu is the FL.
My best guess is that we're going to see both of them in part 2.
It mentions that JSM signed on for both seasons. I don't think they'd just drop her for season 2 of she was already in a contract to do both the seasons. Especially seeing the reactions from the fans and how much support and love she's getting for the role.
Is it like Our FL will not get her power back until she gets her own body (GYJ back)?
I think JSM said that during her last week of filming she shot a lot of fight scenes. Maybe we'll get to see Mu Deok/Naksu get her powers back towards the end of the season.
I saw it too. How we busy rating even in each episode doesn't matter this much anymore 😭🥺
Woah I didn't know we could rate each episode? I thought we could only rate the show as a whole. I went ahead and rated the episodes now! Thanks for letting me know about this feature! 🙌

The yin yang jade would be more useful in this scenario - but Mu Deok/Naksu doesn't have her energy yet to use it.
Master Lee is just above the Chisu level and Jang Uk has already mastered that. I'm guessing we'll see Mu Deok/Naksu getting her powers back in the next 3-4 episodes.
This one, last paragraph.
This is so cool!
