I suspect Scott’s got his own nerd side (like airplanes), he’s just so very quiet next to John, because really anyone is going to seem quiet next to him. Also I strongly suspect Scott’s developed a superhuman ability to tune John out as needed in order to survive 20 years together.
And I’m going to use this as an excuse to post some barrowgill gifs because reasons.
These two dorks so clearly love each other so much.
