I'm looking for a fic I read a few years ago. Kurt has a son, I can't remember if it was mpreg or not. I only remember a few details. His son is mute. I know he meets Blaine later on in the story when his son is a toddler. I remember a scene where Blaine, Kurt and his son went to an aquarium and have a run in with Karofsky. I hope someone knows what fic i'm talking about.
