Jessica Lee Moore was born January 24, 1984 and she also shares a birthday with Dean and the date of both of their birthdays happen a couple of months after Mary's death. She was killed on November 2, 2005 in the same manner as Mary Winchester. She shared an apartment with Sam in Palo Alto and was also a student at Stanford. It is not known what she was studying.
It is Halloween and Jess is dressed up in a sexy nurse costume and goes out for drinks with her boyfriend Sam Winchester, to celebrate his good LSAT score which should guarantee him a place in law school. Later that night, she wakes to find Sam talking to his brother Dean in the living room. The brothers haven’t spoken for some time, and Dean has only turned up because their father has gone missing on what Dean calls a "hunting trip." Sam leaves to help Dean, promising to return by Sunday night. When Sam returns he grabs a cookie from the kitchen. He lies down on his bed, and opens his eyes to find Jessica, eviscerated, and burning on the ceiling.
Sam has a nightmare where he is putting flowers on Jess' grave, and her hand reaches up from the earth and grabs him.
Sam sees Jess on the street, in a long white nightgown. It was unclear if this was a vision or a memory.
When the brothers are attempting to trap Bloody Mary, Sam volunteers for the responsibility of calling her due to his guilt at Jess's death; Dean argues that it won't work as he knows how Sam could have prevented Jess's death, but Sam simply tells Dean that he doesn't know everything.
The cost of doing business, I’m afraid. I mean, sweet little Jessica –- she just had to die. You were all set to marry that little blonde thing, become a tax lawyer with two kids, a beer gut, and a little McMansion in the suburbs. I needed you sharp on the road, honing your skills. Your gifts.
While Sam and Dean are talking with the Publisher of the Supernatural series, she mentions that she found Sam's decision to shoot Madison - "the first woman since Jessica he ever loved" - to be a particularly moving part of the series.
Lucifer appears as Jess in Sam's dreams, trying to convince him that he will never change, and that those close to him will continue to die (an alternate explanation is that Jess is part of Sam's subconscious, i.e. a dream, which Lucifer then invades.)
Azazel was concerned that Sam was losing his potential, and so it was revealed that Brady introduced Sam to Jess with the plan that her death would drive Sam back to hunting. It was Brady who killed Jess, on Azazel's instructions. Clearly his instructions were to make it appear as though Azazel killed her so Sam would recognize the death scene and continue hunting to get revenge.
- Jess shares a birthday with Dean: she was born January 24, 1984 (a couple of months after Mary's death). In an interview Eric Kripke said the reason for this was "...not a creepy, mythology, conspiracy reason. January 24 is my wife's birthday, and it's kinda my valentine to her."
- The studio bosses wanted Eric Kripke to write Jessica as an ongoing character, but Eric just thought it wouldn't work, and he suggested to kill her off, which they liked. Then the studio urged Kripke to make Jessica an evil demon character, who was planted into Sam's life with purpose, and whose betrayal drives him on the road as he realizes, demons are closer to him than he thought.S1Com, p. 13
