Felicia Day and Wil Wheaton have reportedly agreed to appear in several episodes of Eureka.

Neil Grayston, who plays Fargo in the show, told E! Online that the duo have become more than just guest stars.

"Wil was just going to be on one episode and now he's on half the season," he said. "And Felicia's on a lot of episodes. They're like members of the cast."

However, Grayston refused to reveal too many details about the pair's storylines on the show, saying: "Felicia and Wil and Fargo have a sort of thingy happen."

Eureka is expected to return for new episodes in 2011.
