After jj and Emily get married and jj changes her name, she introduces herself as special agent prentiss. This draws the question, "any relation to ambassador prentiss?" To which she says "daughter-in-law" and the person is like "she has no sons???"
This is hilarious. (Although I don’t htink they’d change names because they are Modern Ladies™) But JJ would abso-freaking-lutely get a kick out of this when she’s introducing herself to someone who knows Elizabeth.
Some dignitary at a suave function, “Yes hello. I’m Supervisory Special Agent Jennifer Prentiss”
“Oh, my mistake I thought the Ambassador’s daughter was named Emily.”
And JJ just saunters off grinning. Emily just rolls her eyes every time and makes a note of how cute her wife is. (She often submits to help-mywife about JJ and her antics)
