Now, Smallville has missed many opportunities over the years....but one of the most regrettable lapses happens...
in "Aqua"! As written, AC was originally supposed to be Lex's swim coach! Can you imagine...these two swimming laps together?
AC: "Great form, Lex!"
Clark would lurk around the pool and get all jealous: "What are you doing with Lex? What's your agenda?"
Lex likes making Clark all jealous!
Now, imagine this scene with all three boys wet and wearing speedos:
Everyone, back in the pool!
