Turns out Karen Gillan isn't the only sci-fi superactress to play Pond.
Back in 2011, Firefly alum Jewel Staite guest-starred in the season-seven Supernatural episode titled "The Girl Next Door." She played a childhood friend of Sam Winchester who may have been eating human brains. We won't spoil the rest of the episode for you, but it is worth noting that Staite's character bore the same name as the 11th Doctor's fiery ginger companion.
Though the characters are very different, it is interesting that Supernatural's writers chose to pay homage to a Doctor Who character in such an obvious way. Perhaps next we'll be getting characters named Rose Tyler or Martha Jones. Who knows? We might even get another Captain Jack Harkness if we wait long enough.
