Well, Nack never hold anything against her even when she did what she did. It just shows about that while paying back is satisfying and tempting for some, it's not the only way to move on from difficult times. Not an amazing subplot, but it's okay
The Nack and Mina subplot is creepy as hell. She tortures him for years to the point of nearly killing him multiple times over, but as soon as their fight is over he immediately "forgives" her, and goes right back to his abuser. It's like some horrifying reverse battered wife tale.
