I love exploring storylines that involve a parental figure that isn't really a parent/blood relative and a child, and there's a special place in my heart for how Neverwinters Nights 2 handled it.
So, there's this cold, albeit respectful relationship between the step father Daeghun and your character. There's always been some distance between the two of you. He takes good care of you, he trains you, he doesn't disappear for weeks or anything like that, but he doesn't really love you (though, truth be told, he simply can't realize the feeling he has for you), and you're left wondering what's the reason for this coldness.
He trusts in your abilities thus he sends you on a dangerous quest. He doesn't look concerned in the slightest, so, after you experience a series of hardships, it's astonishing to see your uncle, Duncan, being Daeghun's opposite - welcoming, loud, more honest. The contrast between them is so striking that you may feel more at home with this unknown uncle than the stepfather you've known all your life.
Then, after even more challenges and mortal perils, when you are faced with a war, when you're literally made into a weapon to win this war, Daeghun finally shows up again, but he's still unable to admit his worry for you. He still sees you as the reason he's lost everything he held dear once. But he starts understanding that the quest he's sent you on will eventually kill you. He sees you standing side by side with Ammon Jerro, a former enemy turned ally, and he GETS that you're rubbing shoulders with sorcerers and murderers WAY beyond your level, and these people will destroy you. So Daeghun begins looking after you. He realized he put your life on the line.
And then, and only then, when you're proclaimed dead, Daeghun actually wakes up. He sees you only when you're out of his sight. He gets what the role of the father is only when he loses his child. And that's the beauty and the tragedy of this whole relationship.
