Watsonish

"You don't really want it explained," he said, smacking him on the knee; "you're just being Watsonish. It's very nice of you, of course, and I appreciate it."

I would have settled for a Watsonish role. I don't have to be the main character.

This element is also picked up by Thomas Aquinas (whose philosophy sometimes has a Watsonish quality in relation to Aristotle, whom he calls simply “The Philosopher”).
