We’re loving that Hayley (Phoebe Tonkin) seems to be gaining more power on The Originals as she fights for werewolf equality in the French Quarter. But will the revelation of a family secret throw her off her game, or even change how she sees her newfound werewolf family? We speculate below.

In Season 1, Episode 19 (“An Unblinking Death”), tensions between the NOLA factions will come to a head when a horrific explosion goes off in the bayou, adding to “the hatred and mistrust among the communities.” According to the episode synopsis: “While Jackson and Elijah work to save the wounded, Hayley learns a surprising piece of her family history from Marcel.” We want to know that secret.

So far, we don’t know much about Hayley’s family, other than the fact that she’s the last one in her bloodline. We know they were one of two royal bloodlines within a larger group called the Crescent Clan, identifiable by the crescent birthmarks they are born with. Hayley, whose birthname was Andrea Labonair, was betrothed to Jackson, the son of the other royal bloodline. With the merging of these two bloodlines and the solidification of their clan, the Crescent Clan planned on taking back the city from the vampires who had stolen it from them. Obviously, that didn’t go as planned.

In the 1990s, the Crescent Clan was cursed by Celeste (who was inhabiting the body of Brin Devereaux, at the time) on the request of Marcel. Allegedly, he wanted to punish the clan for fighting against the vampires. The curse reversed the rules of the werewolf curse, making it so the members of the Crescent Clan were only human on the days of the full moon. Hayley recently reversed the curse with the help of Celeste.

So, what’s this epic secret? Given that it’s coming from Marcel, we’re guessing it has something to do with the curse. Perhaps, it relates to the two royal bloodlines, and the reason why Hayley’s was completely wiped out. Did Jackson’s bloodline betray Hayley’s to save themselves?

Another potential subject for the secret: how Hayley managed to evade the effects of the curse and away from NOLA. Hayley was raised by an adopted family and knew nothing of her werewolf heritage until she accidentally killed someone, triggering the werewolf gene. Was Marcel the one who helped get Hayley out of New Orleans, perhaps taking mercy on the small child even after he cursed her entire clan? This would add an interesting dynamic to what is now pretty much a non-relationship.

A third option is that Marcel wasn’t the person who wanted the curse put on the Clan. Could the order have come from another faction, or perhaps from another werewolf clan who wanted power for themselves? There are so many intriguing possibilities that only add to the complexity of Hayley’s character and this entire supernatural society.
