Jae Hee brings Hye In to NTS and questions her about Athena.
I liked the conversation between Jung Woo and Dr. Kwon. Their relationship is one of the things I like about this drama. It's rare that a K-Drama character will open up to others [especially co-workers] about how he/she feels like Jung Woo does. I like that Dr. Kwon is supportive and listens to him and doesn't just tell him to suck it up like many others probably would have.
Andy/Randy (?) pretends to be turning himself in to NTS so he and a fellow Athena member can sneak bombs into NTS headquarters. Son Hyuk holds NTS hostage because he wants to get Hye In back.
