So, with the help of Son Hyuk and Randy, Hye In was able to get away with killing the guard. At this point, still not sure if she's developed a soft spot for Jung Woo or it's just an act.
I took issue with the "death" of Dr. Kim and the events that followed. As Son Hyuk pointed out, it was weird that no one was being held accountable for his death. If Dr. Kim was supposed to be so important, someone should be losing their job [most likely the NTS director].
Now, with that said, I thought it was absurd that the agents were talking about the possibility of the agency disbanding and them losing their jobs because of Dr. Kim's death. That makes absolutely no sense. Even if Dr. Kim had been the NTS director or the President, there would be no reason to disband the entire agency. If NTS is supposed to be an anti-terrorism agency, then there should be more than enough cause for it to exist other than Dr. Kim and the nuclear technology.
