"IRIS 2" Lee Bum Soo made a move that nobody was expecting.

In the 7th episode of the KBS drama "IRIS 2" that aired March 6 featured Joong Won (Lee Bum Soo) taking a powerful shot, flipping the Braun tube.

From NCC, Cheol Young (Kim Seung Woo), Joong Won (Lee Bum Soo) and Yeon Hwa (Im Soo Hyang) arrives in Japan together but from the help of Ray (David McInnis), Yeon Hwa is able to return to IRIS.

Cheol Young then gets attacked by Ray and Yoo Gun (Jang Hyuk) who has lost all of his memories. Cheol Young receives a wound in his arm. And when Cheol Young tries to get help from Joong Won, he says, "We have to find Yeon Hwa" then suddenly points his gun at Cheol Young. With the words, "Thanks for everything" and pulls the trigger.

This episode does not show what happens to Cheol Young but the preview of the next episode showed Joong Won reporting to somebody. Joong Won says, "The assignment is complete."

In the last episode, Joong Won is reunited with Yeon Hwa, whom he loves. He agrees to work with IRIS with Yeon Hwa but his loyalty is unclear as of right now.
