Hearing that his anger isn't some terrible thing he needs to sweep under the rug is a surprise to Fern. In most of his experiences so far it's never been a good thing, and while it's not like Kurt is saying that specifically, to receive the suggestion that he should feel it is... wow, it's weird, and it's a little validating. He isn't completely wrong for feeling this way. He just needs to make sure it doesn't get destructive, and unfortunately for everyone his track record with that isn't so great.

He glances down at Kurt's hand, now a little more thoughtful. "You're making this sound really, really easy." It isn't, he knows it isn't. It'd be a lot easier to just give up right now. Still....

"I think I want to try." He doesn't sound the least bit confident in his own abilities, he's just hoping that trying is a step in the right direction.
