Aaron Echolls: Quid pro quo Mrs. C. ... Quid pro quo.
This is (almost) a direct quote from The Silence of the Lambs. In the movie, Hannibal Lecter says "Quid pro quo, yes or no?" while being in the same situation as Aaron. After saying this, Aaron Echolls makes the exact same famous "sound" like Hannibal Lecter.
