Obvious Revelations

The revelations made in this episode are things that I guessed several episodes ago (either because the twists were easy, or I'm good at this; your call). The killer's motivations are dumb and kind of convoluted. The big bad is revealed, and it's literally not surprising at all (because it's been the same person the whole time, and there was no way this person WASN'T evil at any point, yet the writer treats the reveal like it's surprising). It wasn't bad, but for the penultimate episode, it was sort of a let-down.I will say that Si Mok's phone call with sad Yeo Jin was perfect. Loved it.
