'Ringer': Misha Collins May Hold The Secrets of Siobhan's Past (VIDEO)

Some loyal "Supernatural" fans might have been feeling deprived by the lack of Castiel on your screens this season, but look to another CW show for your tall, dark and brooding fix. Misha Collins -- the man behind our favorite fallen angel -- is set to appear in next Tuesday's installment of "Ringer" (Feb. 21 at 9 p.m. EST) and HuffPost TV has an exclusive clip of his eagerly-anticipated appearance.

Collins' character, Dylan, was previously described as "an important part of the sisters' past" in the episode's synopsis, and the exclusive clip from "Whores Don't Make That Much" seems to lend credence to that fact. He apparently had a contentious relationship with Siobhan in particular, as we see in an intriguing flashback that features both siblings, as well as Sean, the young boy that we've only seen in photos with Siobhan up until this point (perhaps it's her son?). Could Dylan be the child's flaky father, looking to reconnect with his ex in the present day?

Series creators Nicole Snyder and Eric Charmelo hint that the episode is an important one in terms of exploring Siobhan's past and her current vendetta against Bridget. She has long carried a burden of guilt for something that happened to Sean, as the twins briefly touched on in the pilot. Though Siobhan previously confessed to forgiving Bridget for her mistake, as we found out in the Feb. 14 episode, that may not actually be the case ...

The exclusive also sheds a little more light on the startling twist that was revealed at the end of the Feb. 14 episode -- that Juliet, Tessa and Mr. Carpenter faked the sexual assault in order to extort money from Juliet's father, as a way of retrieving her confiscated trust fund. Charmelo and Snyder promise further developments in that scheme, as the loyalty between the trio threatens to fracture. It also looks like Bridget is finally coming close to uncovering some of her sister's secrets, but is Andrew as innocent as Bridget believes he is, or could Siobhan be justified in trying to take her husband down? So many mysteries, so little time!

"Ringer" airs Tuesdays at 9 p.m. EST on The CW.
