The children are surprised to see M-21 with their kidnappers and keep on asking why he's there. Shark asks M-21 if he knows them. M-21 who knows that they'll be in trouble if it's disclosed that he knows them, tells that they've passed by sometimes but are not acquaintances. At this, the children are shocked but Regis approves and repeats the same words. M-21's plan boomerangs as Shark decides to kill the children since they are of no use. Tao tries to convince Krantz to use memory-erasing drugs on them but fails. Krantz too, thinks they should get rid of the children. Overwhelmed at the joy of getting permission, Shark attacks Regis brutally. Unable to tolerate seeing that, Shinwoo places a punch on the right side of Shark's face.
Hammer heads to the safe house to bring some more food and meets Seira. Meanwhile, Rai and Frankenstein visit the spot from where the children were kidnapped and see the traces of fight. Frankenstein suggests visiting the Union research faculty. Rai is not in a good mood (enemies of the children, Beware!)
