|Episode(s)||4.19 Jump the Shark|
In January 1990, Kate Milligan met John Winchester in Windom, Minnesota when he came into the hospital where she worked as a nurse after he was injured during a ghoul hunt. Adam was born on September 29, 1990, although he didn't have any contact with John until he was twelve. Thereafter, Kate and her son had sporadic contact with John who taught Adam pool and poker, took him to ball games on his birthday, bought him his first beer when he was 15 and taught him to drive in the Impala.
Kate and Adam are killed by ghouls in revenge for the killing of their parent by John Winchester during the time John and Kate met. One of the ghouls takes on Adam's form and memories in order to lure Sam and Dean to the town and later teams up with its sibling, in the form of Kate to finish them off. Both ghouls are killed by Dean.
Zachariah promised Adam that if he allowed Michael to possess him, that he would resurrect his mother. After Adam discovers that he is being used as bait to lure Dean into the Green Room, Zachariah still promises to resurrect Kate, though Adam doesn't believe him.
