Ha Ji Won lost Ju Jin Mo's child.
On the 23rd episode of MBC Monday/Tuesday "Empress Ki" (script Jang Young Chul, Jung Kyung Soon, director Han Hee, Lee Sung Joon) broadcast on January 20th, Ki Seung Nyang (played by Ha Ji Won) lost Wang Yu (played by Ju Jin Mo)'s child.
On this day, Ki Seung Nyang was being chased by Yeom Byung Soo (played by Jung Woong In) and was hiding in a cave by herself as she safely had a child by himself.
However, the Yeom Byung Soo gang heard tears of a baby and followed. Ki Seung Nyang had the baby on her back and fled but was pushed to the end of a cliff.
Yeom Byung Soo's subordinate fell with the kid that Ki Seung Nyang had on his back. Yeom Byung Soo shot the arrow to Ki Seung Nyang and Ki Seung Nyang fell together.
Ki Seung Nyang survived thanks to the mirror that Rho Sang Goong (played by Lee Eung Gyung) had given but there was nowhere to know where the kid went.
As soon as she gained consciousness, Ki Seung Nyang went to find the child but there was only the body of the subordinate and no child, as she cried finding that the child was nowhere to be found.
