The son of Harry Mudd who's also an android. Hmmm. Fascinating. How does that happen? Harcourt! Harcout Fenton Mudd, what have you been up to? You answer me!
And at the end of the movie, as an homage to "The Squire of Gothos", Stella comes for little Harry, takes him by the ear, tells him he's been a very very bad boy and that he's grounded for a month, apologizes to Kirk and Spock, and takes Harry home.
