It is about time our characters start getting a clue about the fact that this case involves human cloning and I am not surprised to see who the ones making this discovery are. Seong-joon's hinted poor health takes a turn for the worse, leaving Deuk-cheon and Mi-rae hoping for his recovery. Meanwhile, Jo-hye tightens her grip on the situation.
Now is a good time to meet our mystery players, but I am happy to see them remain mysterious for now. The fact that we are dealing with two clones and one original is thankfully confirmed and although we still have the shared memories to deal with, the series is not going off the deep pseudo-scientific end just yet. The original doctor's body is clearly important enough to keep and so I stand by my assumption of it containing valuable science.
