The final clean-up takes place pretty quickly. Really, once it's established that the right people were digging in just a little deeper, and that most of last time's cliffhanger was just a matter of dramatic license, there really isn't any direction for Gi-joon to go except for straight down. There is, naturally, also the gratification of seeing all the other villains brought in one by one and punished for their transgressions.
Of course none of that takes very long so the real focus for the final episodes of "My Sassy Girl - Drama" is on the reconciliation between Woo and Princess Hyemyeong. Which initially disappointed me. Not that there's anything wrong with that story arc, just that the whole issue of Princess Hyeomyeong's mother coming back to the palace is surprisingly glossed over. I thought we'd get more focus on that, considering Princess Hyemyeong and her brother now share the unfortunate fate of thinking their mother is dead- but Prince Wonja is just left in the lurch.
