Dawson Casting: It's implied that Bobby Lee is 16; Michele Greene – who played the orphan whose tomboyish clothes hides an awesomely beautiful teen-aged girl – was 20 when she filmed this episode in 1982.
Heartwarming Orphan: In more ways than one with Bobby Lee. Incidentally, orphans (particularly, those fitting the trope) and children whose father had died would become somewhat of a semi-regular plot device during the final three years, with the Duke family interacting with the affected children and trying to make a positive difference in their lives.
Quicksand Sucks: Bobby Lee absent-mindedly falls into a patch of quicksand – there's quicksand in Georgia(?) – and Coy just happens to be in the area to rescue her.
