Not all of "Smallville"'s stories this season came from the writing staff. Mark Warshaw, who was head of the internet team that wrote the online Smallville articles for the Ledger and Torch, which interwove the television episodes with online, fictional newspapers that continued the stories from the show, was the one that came up with the idea behind "Skinwalker". Warshaw's story was about a Native American girl who falls in love with Clark, while at the same time revealing Clark's destiny to him. The story was bought and given to Kelly Souders and Brian Peterson on the writing staff to work on a screenplay. The episode had a significant role in the series, as it introduced the Kawatche caves—which held the Kryptonian language written on its walls—and explored Clark's origins, while at the same time posing the question that people from Clark's homeworld may have visited Smallville before Clark arrived on the planet.
