I've always wanted an old original werewolf to be the big bad in the originals, since Marcel is a vamp as are Elijah and Rebekah and even Klaus (partially) then Original werewolf siding with a witch or witches to destroy vampires would be the best storyline.Also with the whole idea of power , respect and a throne definitely an original wolf needs to come onto the scene.Now that TVD has Silas an immortal who is not really technically a vampire , what stops the mythology of the werewolves from having an immortal werewolf among them? I've been thinking of an immortal werewolf idea
One that I came up with some months ago..

The other I'm musing over is one that can be developed in the course of this season .Like say there is a clique of werewolves that is allied with a dark coven that want to have their curse lifted and they are told that they can only have their curse lifted if they kill Hayley since she is carrying the child of the only immortal werewolf to have ever had his curse bound ... their curse would forever be bound with the sacrificial death of Hayley. However we find that since Sophie is tied to Hayley when they attempt to do so the spell does not work out because it's not just Hayley but a witch's life is interfering with the spell.So at the end we have Hayley surviving with the baby ,but a loophole is created that all the werewolves who were part of the deal turn normal except one of them who is in fact from Hayley's lineage and the curse has multiplied in him/her animating him/her as some superwolf as the main antagonist for season 2.This whole arc does not have to be elaborated this season we can say the immortal or super werewolf is almost an accident due to a spell gone wrong as the wolves' original intent was to cure their curse not create a super werewolf.
