Amid growing doubts, episodes 9 and 10 revealed that the warden (played by Jung Jae Sung) is in fact working for Big Mouse. In episode 8, Jerry (Kwak Dong Yeon), the character we suspected the most, got off the radar as he faced death while trying to save Park Chang Ho (Lee Jong Suk). However, Jerry was seen alive and fine in episode 9, reigniting the doubts as he tore off the notes sent from Chang Ho. The dirty secret of mayor Choi Do Ha (Kim Ju Hun) was also revealed. Although we all thought that he was secretly helping Chang Ho, he was the accomplice of the man who killed professor Seo Jae Yong (Park Hoon) who has a grudge against the elderly (Jeon Kuk Hwan). The drama briefly showed how he became so vengeful against the old man. Observing things from Park Chang HoŌĆÖs perspective, viewers are focusing on finding the real con man. At the same time, the fact that Park Chang Ho canŌĆÖt be wholly trusted is what makes viewers stay tuned in the drama. Meanwhile, more mysteries are left to be unsolved about why Big Mouse is obsessed with professor Seo Jae YongŌĆÖs thesis paper and how Gucheon prison and hospital are connected to each other. The series is expected to keep viewers in its grip with a plot filled with twists and turns. Source (1)
