Ask him what *he* thinks of the "Surrender Date".
OR
If you think it's safe to flirt, you could say you watched the show and that the idea of a Surrender Date really piqued your interest...and then wait to see what he says.
OR
You could keep it strictly on the friends level and simply agree that you can see how damaging it is to have that sort of dynamic, and then sincerely apologize for the part you played in that roll.

Have you watched the show yet?
