April 17, the 19th episode of the KBS drama "IRIS 2" featured the long awaited reunification of Jung Yoo Gun (Jang Hyuk) and Ji Soo Yeon (Lee Da Hae).

Jung Yoo Gun and Kim Yeon Hwa (Lim Soo Hyang) team up while Ji Soo Hyun and Seo Hyun Woo (Yoon Doo Joon) move together this day. Both parties begin to chase down Yoon Shi Hyuk (Lee Joon) but in the process, Jung Yoo Gun and Ji Soo Yeon reunite with guns pointing at one another. Kim Yeon Hwa and Seo Hyun Woo keep their eyes on them from a distance.

Ji Soo Yeon worries about Jung Yoo Gun's health and says, "What happened with Kim Yeon Hwa? Can you believe it?" Jung Yoo Gun replies, "She is helping me catch Yoo Joong Won (Lee Beom Soo). She doesn't even have a place to go without me."

Jung Yoo Gun continues, "The hard disk can be checked only through the main server at the NSS headquarters. This is a huge favor..." and Ji Soo Yeon replies, "Are you really not going to return to NSS?"

Jung Yoo Gun explains, "I am wanted by the government. Just be patient until I catch Yoo Joong Won. I'll confess after that." He then adds, "Thank you and I'm sorry" and begins to leave. Ji Soo Yeon finds herself unable to hold him back and says, "Take care of yourself".

This brief reunification of the two saddened the viewers.
