The episode is tentatively titled "The Girl Next Door" and features the return of young Sam Winchester. Young Sam is played by 14-year-old Colin Ford, who has appeared in several Supernatural episodes: Season 3's "A Very Supernatural Christmas," Season 4's "After School Special" and "When The Levee Breaks," and Season 5's "Dark Side of the Moon."
"The Girl Next Door" involves Sam having flashbacks to when he was 15, when a girl named Amy saved his life and tried to convince him to run away with her. In the present day, Sam and Amy meet again and he finds that Amy has a "normal" life with a son, a steady job, and a mortgage. Needless to say she is very surprised to see Sam again.
The episode is expected to air on October 7.
