Repost from Allkpop.....
In Ha and Dal Po made very admirable choices this episode. In Ha was willing to give up her entire reporting career and expose evidence that would incriminate her superiors for both Dal Po's sake and for the sake of justice. Dal Po, on the other hand, refused In Ha's piece of evidence because he didn't want to see her dreams destroyed. This pairing proves that when they're not being wishy-washy and going on-and-off, they're a mature couple that cares deeply for each other.
They also represent the polar opposite of Cha Ok's relationship with Dal Pyeong, the history of which was revealed in this episode. While In Ha and Dal Po are willing to make sacrifices for each other, even if it means losing their career or a chance to enact revenge, Cha Ok responded to Dal Pyeong's situation rather selfishly. When Dal Pyeong quit his job after becoming a "whistle-blower," Cha Ok deemed Dal Pyeong to be "pathetic" and strove to be better than him. She ignored her family, gave up both her husband and daughter, and even abandoned her sense of morality all for her career, for a chance to become the first female captain of the team.
Seeing her daughter being selfless not only for Dal Po but also for her own sake, to apologize in her stead, Cha Ok finally seems to fully regret her choices, hence her tears. I'm thrilled that Dal Po suggested that Cha Ok be the one to make things right and reveal her own wrongdoings to the world. She would finally be doing something selfless, not only to make up for what she did to Dal Po but also to prevent her daughter from having to ruin her own career. Cha Ok would finally be the mother she failed to be after all these years. I find this to be a pretty awesome chance for redemption. I can't wait to see what Cha Ok does with it in the next few weeks!
Cha Ok seems visibly rattled when Ro Sa says she wants to start using her daughter. She knows that if Ro Sa tries to get a hold of In Ha, then history just might repeat Itself.
Which is why when Dal Po makes this ingenious proposal...
... Cha Ok just might do it.
