The official synopsis reads as follows:

Sam (Jared Padalecki) and Dean (Jensen Ackles) investigate a string of suicides committed by people with little in common other than the identical, grisly method of death - slow, self-administered disembowlment. All of the victims were members of a Catholic church and had recently given confession, leading the brothers to suspect the priest (guest star Stephen Daniel Curtis) is somehow involved. Meanwhile, when Crowley (Mark Sheppard) captures Olivette (guest star Teryl Rothery), the leader of the Grand Coven, Rowena (guest star Ruth Connell) pleads her case to be allowed to practice magic freely again.

There is some good news for fans as favourite character Bobby Singer returns to help the Winchesters in the show.

According to Variety, Jim Beaver's character will appear in the 1 April episode titled, Inside Man.

According to the official synopsis of the episode, "Sam (Jared Padalecki) and Castiel (Misha Collins) need a little help from someone in heaven, so they turn to Bobby (Beaver). Elsewhere, Dean (Jensen Ackles) and Rowena (guest star Ruth Connell) face off.

Beaver's beloved character was killed in the season 7 episode Death's Door, but has made several reappearances in spirit form since then.
