Here's what I don't understand....

You have just been in an accident which now you know was purposely done and the victim, the person who has the antibody is NOT being protected?!!! What kind of sense does that make? I did not understand why Kim In Chul was in a regular room and unprotected. If someone understands this, let me know! I couldn't figure why!! So what happened at the end of the episode made perfect sense. You, the bad guys, failed in killing him so let's kidnap him! Bad CDC for not protecting your guy!!
