[ Gwen's decently insightful, and has a lot of experience in making people uncomfortable with the things she says or how much she knows about them. So, she clocks that uncertainty in Kurt's laugh and reels in her enthusiasm. ]

I'm sorry. I'm not making things awkward, am I? I promise, I can try to explain how I know all this stuff... [ Hopefully in a way that won't either break Kurt's brain or make him think she's delusional. ] But it actually does seem to be working!

[ She can wiggle her toes again now! Look! ]
