"So geeking out about space travel is what does it for you, huh?" Jacob says afterward, before the stickiness becomes quite uncomfortable enough to get off the bed. "I knew there was an astrophysicist buried deep within that grubby biologist exterior."
"I think you’ll find the biologist is often buried deep within the astrophysicist," Kurt says, and Jacob punches him in the spleen on principle. Kurt laughs and ruffles Jacob’s hair—which, first of all, Jacob is not a kid no matter how many years or published scientific essays lie between them, and second of all, Jacob knows where that hand has been in the last half hour. Gross.
Kurt sighs and sits up, then hesitates on the edge of the bed. “I wanted to be an astronaut,” he says, and it doesn’t really sound like a joke but Jacob can’t see his face to be sure.
