I get the feeling Hayley's bloodline is the original bloodline and Eve may reveal that but she may also reveal that Hayley's child will be more powerful than Klaus because unlike Elijah and Rebecca who can turn humans vampire or (Klaus who can only turn humans vampire or werewolves hybrid), the child due to vampire heritage will be able to turn humans into either triggered werewolves or hybrids.For this reason I think Eve and other surviving werewolves are very protective of Hayley and want this baby as much as Klaus does and they feel due to it's original werwolf heritage through Hayley she and they may have an ultimate weapon against vampires.In fact I think this is the shocking revelation in 'Reigning pain in N.Orleans'. I really feel like this would create an intense dilemma between all the characters .Klaus may not be too amused with an being potentially more powerful than himself.This would actually pass Mikael's predicament to Klaus and we see the path he takes.Elijah I think may stand by Hayley as he puts family above petty powerplays. Rebecca may be the one torn as she knows this would endanger Marcel and actually turn Marcel against all her family.
What do you think? I think it's really likely and would add something new to the mythos and bring the vampire-werewolf feud to the fore again.I'm sure werewolves cant wait to get Hayley on their side
