You can pretend all you want, Sammy. But sooner or later you're going to have to face up to who you really are. One of us.
Dean: Dad hasn't been home in a few days.
Sam: So he's working overtime on a Miller Time shift. He'll stumble back in sooner or later.

Written by Eric Kripke.Directed by David Nutter.Airdate: September 13, 2005.Dean asks his brother to join him, when their father disappears investigating a supernatural creature in Jericho, California.On November 2, 1983, Mary Winchester was killed in the family home in Lawrence, Kansas, by an unknown supernatural creature, in front of her husband John and her sons, Dean and Sam. In the present day, Sam is a law student at Standford University with a loving girlfriend named Jessica and a promising career—until Dean arrives, asking for help in tracking down their father. John has been on one of his frequent "hunting" trips, where he tracks down and kills supernatural creatures: John and the boys have been doing this since their mother's death, but Sam left the hunting life after a falling out with his father. John hasn't returned from his latest trip, and Dean is worried. Sam agrees to help Dean look for their father.The brothers track down the last creature John was hunting, a Woman in White named Constance Welch, who had killed her children and then herself after learning her husband was cheating on her. Constance's ghost kills unfaithful men who drive across the bridge she jumped off of. Sam and Dean force her to return home to confront the waiting spirits of her children, and she vanishes, screaming. They also find John's journal, full of all his information on various creatures as well as the record of his hunt for the creature that killed Mary, but they can't find John.Sam returns to Stanford, but when he returns to his dorm, he finds Jessica suspended on the ceiling, bleeding and consumed by fire: the exact same way his mother died. Now that it's personal, Sam agrees to partner up with Dean and return to hunting, hoping that along the way they can find their father and finally destroy the creature that killed their mother and Jessica.
Big Brother Instinct: Dean saying good night to baby Sammy, and taking him out of the house in the fire.
Book Ends: The beginning of the episode has John's wife gutted and roasted above Sam's crib while she's wearing a white nightgown. The ending has Sam's girlfriend/would-be fiancee gutted and roasted above hers and Sam's bed while she's wearing a white nightgown.
Characterization Marches On: In retrospective, Dean looks more immature in his first appearance than portrated later. For instance he breaks into Sam's apartment, assault him in the dark to test his practice, flirts briefly with Jessica, then only reveals he came because their father went missing. Later Dean takes those things seriously and would directly tell Sam what is going on.
Cool Car: Dean's 1967 Chevrolet Impala with an armory in the trunk and a tape deck.
Samantha Smith who plays Mary Winchester, also played Daphne in Dark Angel.
Sarah Shahi who plays Constance Welch, also plays Jenny in Alias, and Sadia Shaw in Dawsons Creek.
Jamil Walker Smith who plays Sam's friend Luis, will go on to play Master Sergeant Ronald Greer in Stargate Universe.
Homicide Machine: The ghost sends the Impala after the Winchesters, and they have to jump off Sylvania bridge to avoid getting crushed. Dean ends up covered in mud, but it is not baby's fault. She was possessed.
Horror Doesn't Settle for Simple Tuesday: A double-whammy: it's Halloween (October 31st) and later on the anniversary of their mother's death (November 2nd, which is also All Souls Day or the Day of the Dead).
White Sheep: The source of Sam's two-year-long estrangement from his family is his decision to go to college.
Woman in White: Constance Welch's story is in the tradition of La Llorona and many of the other women in white who haunt rivers and lakes. The ladies in this episode start the fine Supernatural tradition of white dresses showing that the character wearing said dress is either evil, dead, or both.
