Ha Ji Won realized that Jun Guk Hwan didn't die.
On the episode of MBC Monday/Tuesday drama "Empress Ki" broadcast on January 7th, the Empress (played by Kim Suh Hyung) was sure that Yeon Chul (played by Jun Guk Hwan) had died of poison.
This was planned by the empress so that when Yeon Chul died, Dang Ki Se (played by Kim Jung Hyun) would be ushered out and Ki Seung Nyang (played by Ha Ji Won) and Wang Yu (played by Ju Jin Mo) also thought that everything was going smoothly.
However, Ki Seung Nyang realized that the tea going into the empress's chambers was Kam Doo Soup and confirmed that Yeon Chul was the only person eating this and when Tanasili (played by Baek Jin Hee) ate peas, she would get hives.
At this, Ki Seung Nyang realized that Yeon Chul was surviving the poision because the Kam Doo Soup had a detox effect and to stop Wang Yu's strategy, she went and told this to Ta Whan (played by Ji Chang Wook) as well.
