The Third Mikaelson Sister

We know about Rebekah and we know about Freya. Now it is time for the third original sister to come to light.
Alayah Mikaelson. The baddest of them all. When Klaus dagger-ed his original siblings Alayah was one of them but she was different, she never was undaggered, at least not for long periods of time. And there was a reason for it, she was simply too much of a liability. Klaus was known for being the baddest original, the one who is ruthless and kills with no remorse, the one who's very name would run fear through the strongest of warriors but that was only because Alayah was in a box. Now it is time to wake her, the prophecy says she is in danger too and the siblings need as much help as they can get in order to stay alive. However her awakening isn't with out risk. Rebekah fell in love with Stefan but Alayah fell in love with Damon many years ago in the twenties when he was in New York, however her brother Nicklaus ripped that love away from her with a dagger that has remained in her till today. With Aurora holding Rebekah captive in the ocean Klaus and Elijah both agree that another original in the game will increase their odds and undagger her. However they ignore her extremely close bond to her fallen brother Kol and dont take in to account the way it will take a toal on her already fragile state. All the brothers know is Aurora was always scared of Alayah and she had every reason to be ann the brothers knew they could use her former love for Tristan to exploit the co-ordinates of Rebeakah's body.
