'Five Fingers' Chae Shi Ra's Child Is Alive?

In episode 15 of the SBS drama 'Five Fingers' it was revealed that Chae Young Rang's child might in fact be alive. 

Chae Young Rang (played by Chae Shi Ra) and Na Gye Hwa (played by Cha Hwa Yeon) are arguing about Chae Young Rang's former husband Yoo Man Se (played by Jo Min Ki) when Na Gye Hwa brings up the child that Young Rang and Man Se had together, upon hearing this Young Mang says "If you are planning to use a dead kid to get us back together, forget about it instantly!"

Na Gye Hwa responds "What if... The child is not dead but alive." Young Rang goes into a state of disbelief until Na Gye Hwa says "What if he was alive? What would you do?"

Episode 16 has already aired and hopefully soon questions will be answered about who Chae Young Rang's child is.
