Supernatural Preview: The Winchesters Tackle Some 'Good Old Fashioned' Ghosts

Supernatural returns from its hiatus on April 20 with five new episodes in a row until the end of the season. This week's episode, "Of Grave Importance", "...really takes us back to our roots," executive producer Robert Singer explains, "It's a good old fashioned ghost story."

The Winchesters are summoned to help by an old hunter friend named Annie, but she's disappeared by the time they roll into town. They look into the case and realize that a lot of teens were disappearing around the old Van Ness House, which is, apparently, one of the most haunted houses in the country. The brothers are rather surprised, however, when the house doesn't show any signs of murder.

Meanwhile, the last episode revealed that Bobby is still sticking around as a ghost. But he's getting frustrated that he can't really communicate with the boys, as you can see in this sneak peek. But EP Singer warns that the boys might not exactly want a ghostly partner. Not want Bobby?! What is this madness?!

Watch a producer's preview below for the April 20 episode of Supernatural, airing at 9:00 p.m. ET/PT on The CW.
