It has been known for a long time that the Winchester Brothers of Supernatural were destined for their life fighting demons and monsters, and even at times, angels, but for a long time they—and the audience by extension—believed it was solely because of their mother, Mary, who came from a long line of hunters and was later killed by a demon, setting their father on a path of revenge. What “As Time Goes By” is out to show us all, though, is that their destiny cuts so much deeper than that.
In “As Time Goes By,” Sam (Jared Padalecki) and Dean (Jensen Ackles) are shocked to see a man show up in their hotel room—a man who claims to be their grandfather, Henry Winchester (Gil McKinney). He time-traveled using a blood sigil that was supposed to take him to his son, John. But since John is dead, it dropped him at the feet of his next of kin. Literally.
“We spent time with the other side of the family, and we wanted to bring it full-circle,” Supernatural executive producer Bob Singer said during a special screening and Q&A in Los Angeles, Calif.
