Saw this. So this explains how Park Jin and his minions didnt recognize Naksu right away. She had a different build as Jin Mu mentioned. Ever since Part 1 ep1, they meticulously made her look "tall". Even the eye mole was part of the plan. (Sorry if this was already posted, havent keeping up with all the posts here. ) 😊
Healing took years for current JBY. So I guess healing takes time. And would come back to my initial answer - Naksu didnt do it on her own. Master Lee had to use his energy too.
Im still thinking - how is GYJ falling short of JSM? The difference I can find is the provincial accent. So are they expecting new Naksu to speak in accent too? I mean, for a rookie actress, GYJ is doing great. For every scene that she's in, she captures the emotions needed for that scene, nothing more or less.
Will we ever see justice for JBY though srsly. Born blind, abducted as a child, nearly killed by her own father,…
I feel you. Lets see if the writers have something in store for her until ep10. Maybe she was a reincarnation of Jin Seol Ran. Maybe she'll miraculously appear again. Haha.
We may also see at the brighter side: - About being blind, lets consider it as a gift. I cant imagine how current JBY's sight when she can see everything during the day while also seeing bright light (energy) amongst people. Thats like staring at multiple bulbs. - And, she had two moms who very much loved her. She didnt have to endure the pain of a tracking thread, be imprisoned by your own so-called "mother", or being denied of your own memories.
