Hayley and her unborn baby are going to have a tough time in the final three episodes of Season 1 of The Originals. Not only are the witches after her and Klaus’ spawn, but her pack is also waging war against her baby daddy and the vampires, which isn’t going to help her stress levels. But as this newly released Season 1 poster — featuring Klaus and Hayley — implies, Klaus will do anything to protect his unborn heir.

We know that in Season 1, Episode 20 (“A Closer Walk With Thee”), Hayley and “her unborn baby fall into peril” during Father Kieran’s celebratory wake. And, “in order to save Hayley, Klaus and Elijah enlist the help of Genevieve who struggles to maintain control over Davina and the other young witches.” Could Hayley’s “surprising enemy” be Oliver? After all, he was the one who hired the suicide bomber to come scare the werewolves into action. After he killed Eve in last week’s episode, we’re afraid he may have snapped. And what better way to get at the vampires than kill Klaus’ heir? We can’t wait to see Klaus and Elijah team up to take down this psycho wolf.

Meanwhile, daddy-to-be Klaus will start suffering from nightmares of his father Mikael as Hayley’s due date inches ever so near. Klaus is then “forced to examine his troubled relationship with his own adoptive son Marcel.”

Here’s hoping Klaus can pull himself together for the birth of his daughter. She’s going to have enough enemies to deal with after she’s born — she doesn’t need her father to be one of them.
