John's always thought of brilliant scientists in numeric terms, all equations and insightful formulas, but Rodney's nothing like that. Rodney is fast and loud, full of hyperbole and clever insults. He may study science, may find the saving equation, but at his core, Rodney is words: imaginative and entrancing.

I love this line. It is very much like Rodney and yet this wonderful story is sweet, and I can imagine John charming Rodney to calmness.
