EyeCon, a fan-friendly science fiction/fantasy/anime convention to be held April 4-6 in Orlando, Florida, has added Jim Beaver to its list of Supernatural guests. Jim Beaver, acclaimed for his role as Ellsworth on HBO's Deadwood, portrays hunter Bobby Singer. Bobby was a friend of John Winchester, before they became estranged (something the show hasn't given us the full story on yet), and often offers help and guidance to Sam (Jared Padalecki) and Dean (Jensen Ackles). With his caustic wit and massive library, as well as Jim Beaver's believable performance, Bobby is a huge hit with Supernatural fans.

Previously announced guests at the convention are Jared Padalecki (Sam Winchester), Sandra McCoy (who portrayed a crossroads demon), Alona Tal (Jo Harvelle), Samantha Ferris (Ellen Harvelle), Chad Lindberg (Ash), and Gabriel Tigerman (Andy). The list also includes Steve Carlson, who wrote the song "Night Time," used in the first season episode "Provenance." The convention will feature signings and a screening of Jensen Ackles' upcoming film Ten Inch Hero.

(The rest of the article contains spoilers for episode 3x10, which airs Thursday, 2/7).

A while back, the fansite Supernatural.tv pointed us to an inteview Cult Times had with Eric Kripke revealing that episode 3x10 would feature Jason Voorhees. Yes, that Jason Voorhees, of Friday 13th fame. Executive producer John Shiban later confirmed that it turned out there were problems obtaining the rights. However, he implied the character might be in there somehow.
"That would be cool," Shiban told the website ShockTillYouDrop. "I don't think I'm giving anything away when I say it's an episode about dreams and the dreamscape, so you face your nightmares. You'll have to see how we work it in."

In the latest development, IF Magazine spoke to executive producer McG (Charlie's Angels). McG was coy on the subject, but dropped this hint: "It’s a giant surprise in relation [to] that, so you have to stay tuned for that. I can’t even talk about that. That show, we go to such lengths to hold on to the mythology and be respectful of the secrets and twists and turns. And [creator Eric] Kripke has that all figured out and it’s going to surprise you."

Episode 3x10, titled "Dream A Little Dream of Me," involves nightmares, and will reveal Bobby Singer's backstory and how he got into hunting. It's also a turning point for Dean. "Right now he's accepting that he's going to Hell and he's unwilling to do anything to stop it," Eric Kripke said in an interview with TV Guide. "That changes 180 percent in Episode 10. Something big happens to him that makes him realize he desperately wants to live and he desperately doesn't want to go to Hell."
