Fic #1: In this one, I remember Kurt finally telling his father about what happened with the crush on Finn and the conversation about Sam and how Finn basically accused Kurt of being predatory after which Burt was furious about how different this was from what Finn had told them.
Fic #2 In this story, Finn has something bordering on obsessive feelings for Kurt. He's not in love with him, but doesn't want anyone else to have him either. If I'm remembering correctly, this finally comes out in front of some of the other New Directions in the auditorium. Finn has been acting friendly to Kurt but sort of expected him to help with whatever Finn felt like asking for and might have even tried to sabotage Kurt's other relationships.
