There is more to the story of The Darkness in the future episodes of "Supernatural" season 11, based on Jensen Ackles's that he and the season's biggest baddie will share a very interesting relationship.

Both he and The Darkness formed a special bond during the process of removing the Mark of Cain from his body last season. But according to Ackles, one of them can still get injured without having to affect the other, since their connection does not involve dark magic or anything like that.

"We will see... what exactly that relationship is" Ackles revealed to TVLine. "I don't think that he knows what to make of it. What it all means and how it's all going to tie into his destiny and his future and what that means for the brothers, he's very nervous about. Obviously, those nerves are something that he's going to be hiding, but we will see it get fleshed out a bit."

In the recent episodes of the long-running fantasy drama, The Darkness takes the form of a young girl named Amara (Yasmeene Ball), who is believed to be the cause of several mischiefs that Dean and his brother Sam (Jared Padalecki) had to investigate. Among these is the one that will happen in the upcoming episode titled "Thin Lizzie," in which a series of murders takes place inside the infamous house of a controversial murderer that is now being used as a bed and breakfast.

According to the synopsis of the episode that will air on Wednesday, "Sam and Dean investigate a series of murders at a local B&B that also happens to be Lizzie Borden's old home. When a local man, Len (guest star Jared Gertner), tells them he saw a little girl around the B&B around the time of the murders, the brothers realize Amara may be responsible."

"Supernatural" season 11 airs every Wednesday on The CW.
