Empress Ki TaNyang BTS Episode 47: Argument Scene/"I Can Eat" BTS

  Original scene:

This scene, I consider as argument scene, because Ta Hwan argue with Ayu and Seung Nyang. First, Ta Hwan says to Ayu that he must be strong but Ayu argue that his mother (SN) teaches him to protect the weak. Thus, caused TH to argue he can't be like that because the weak will lose to the stronger one and then caused Ayu to cry. Seung Nyang then comes to console Ayu and confront TH.  At the scene, you can really sense the difference and the coldness from both sides, Ta Hwan and Seung Nyang. They argue over Yuan and Goryeo origin and also about Bayan's plan to make Yuan stronger. The scene is also accompanied by chilling music to add the atmosphere to the story.

Then, MBC released this BTS video that proves otherwise. The casts no longer cold toward each other. Ji Chang Wook was definitely the joker here and he likes to play with Kim Jin Woo (Ayu) and tease Ha Ji Won. 

Behind the scene:

JCW taps HJW, shaking her out of her reverie.

HJW: What?

JCW: What are you doing? / Are you tired? (DC fans couldn't tell)

HJW: I was pondering something. 

JCW: Ooh...

Looking at how JCW avoid from HJW's hand (that was effectively going in for a knock), he must've developed a fear of her strength (washing-up scenes BTS). 

JCW's delivery (problem with the tone of voice) of his previous line 
JCW: "Gwibi, don't meddle in state affairs," led to HJW bursting into laughter
HJW: "Why can't I meddle when you don't have any abilities?"

JCW: "I can eat." 

 HJW replies: "What [can you eat] ?"

JCW turns back to shake her, as HJW says "This is really funny."
