Sam and Dean are contacted by one Adam Milligan who claims to be John Winchester's son. The boys immediately suspect a demon trap and go to investigate. Adam turns out to legitimately be John's son and Dean is furious that John kept Adam's existence from them as well as sheltered Adam from the hunting life. Meanwhile other supernatural forces are at work, which lead to a tragic twist that neither Sam, Dean, or their new sibling could have guessed. Written by

The Winchesters meet Adam at Cousin Oliver's restaurant. This is a reference to the character "Cousin Oliver" in The Brady Bunch
(1969). Cousin Oliver was brought in during the final season of the show in an attempt to recapture the cuteness of a young child, as all the original cast had gotten much older. Many fans consider this to be when The Brady Bunch
(1969) itself "jumped the shark." See more
