The residents of Haven has a new baddie on their hands, but as bad as Mara may be, she may hold the key to curing the Troubles for good.

'Haven' Season 5 To Delve Into Core Characters, One Major Cast Addition

William (Colin Ferguson) is out of the picture, but his partner in crime has hijacked Audrey Parker's body and it doesn't look like she will be returning it anytime soon. The longer Mara sticks around the supernatural town, the more damage she can cause.

Alternately, Mara extended stay could give Nathan, Duke, and Dwight enough time to figure out how to reverse her negative effects.

Surprising New Guest Stars Promised For 'Haven' Season 5 Episodes

"She created the troubles, she's got to know how to end them," Duke can be heard saying in a new 30-sec promo.

Hopefully she won't need any help from William. Ferguson's character is off in an alternate dimension, and TV Line claims he won't have a chance to come back during season 5.
