The Elenium/Heartwarming

In "The Ruby Knight": Kurik acknowledging his illegitimate son Talen.

"Are you ashamed of me, Father?" Talen asked in a small voice, his face downcast.
Kurik looked at him. "No, Talen," he said, "actually, I'm not." He put his burly arm around the boy's shoulders. "This is my son, Talen," he said defiantly, "and if anybody wants to make an issue of it, I'll be more than happy to give him satisfaction and we can throw out the nonsense about the nobility and the commons not being allowed to fight each other."

- Almost as much as that, the other knights immediately congratulate Kurik on having such an amazing son. This drives Talen into Sephrenia's arms, tears flowing.
