Bobby & Rufus Returning to Supernatural

According to an article on TV Line, Jim Beaver and Steven Williams will be reprising their roles as Bobby Singer and Rufus Turner in episode 11x16. Exec Jeremy Carver commented,

[Dean and Sam] are going to be investigating an old case that was once investigated by Bobby and Rufus. There’s a lot of great throwbacks to things that happened... the wonderful relationship between Bobby and Rufus. That’s going to be a really neat episode.
