So, now we're in Japan and the search for the kidnapped Dr. Kim is on.
NTS initially heads to one location but Jun Ho realizes they've been sent to the wrong place. He goes off on his own and is able to reacquire the NSC. NTS is unable to rescue Dr. Kim. In part, due to Hye In warning Son Hyuk and Athena about the movements of NTS.
Dr. Kwon [NTS director] meets with Son Hyuk for more of their usual banter. Jun Ho tells Dr. Kwon that, without a doubt, NTS has a spy and info is being leaked out. Looks like Ki Soo is headed to Japan as well. Jung Woo receives a text from Hye In that turns out to be a trap.
