Not only is Smallville’s Black Canary Alaina Huffman in the January 30 Supernatural, which is titled “As Time Goes By”… we also meet Sam and Dean’s paternal grandfather… maybe. Here’s how The CW describes it:
SAM AND DEAN MEET THEIR GRANDFATHER — Sam (Jared Padalecki) and Dean (Jensen Ackles) are stunned when a man who claims to be Henry Winchester (guest star Gil McKinney), their grandfather, suddenly appears in their hotel room demanding to know where he can find John Winchester. Henry has time-traveled to stop a demon named Abbadon (guest star Alaina Huffman) and was looking for John’s help. Through Henry, Sam and Dean learn more about their father and the Winchester blood line. Serge Ladouceur directed the episode written by Adam Glass (#812).
The network has now released some spoiler photos. Enjoy:
