One of my favourite scenes from episode 4 tonight, of Mu Yeom in the interrogation room with Yang Cheol Gon (Sung Dong-il) after he was arrested as a suspect at the scene of the second murder case. The victim had been killed by Ryu Tae Oh (Lee Joon) and buried in the hay stack.
Since Mu Yeom’s DNA could not be matched with a non-existing sample from Gapdong, Cheol Gon had no choice but to release him. Using this chance to get Mu Yeom out of their unit, Cheol Gon offered to release him on condition that he signed a resignation letter.
Wonderful acting by Sang Hyun, especially with the multiple emotions so palpable from his eyes …… derision, sadness and anger.
