If there are two things that tend to go hand-and-hand in vampire mythology, it’s vampires and coffins. Surprisingly, The Originals is somewhat sparse on the coffins. They usually only pop up when Klaus (Joseph Morgan) has daggered one of his siblings. Which is why we’re so worried about Joseph’s recent tweet.

“Filming a scene with a coffin,” Joseph tweeted earlier today. Uh oh. Does this mean Klaus has daggered Elijah (Daniel Gillies)? There seems to be a good chance given the direction their relationship is currently heading. Though the brothers may seem relatively amicable on the surface, Klaus has started plotting behind Elijah’s back. While Elijah forges a peace treaty between the different factions of the city, Klaus works to undermine that peace by working with the oppressed werewolves to hatch a power-grabbing plan. Does this plan end in Klaus’ needing to dagger Elijah and stick him in a coffin to keep him quiet? Because, we’re just saying, a lot of Klaus’ plans tend to.

Of course, there could be another explanation for the coffin on set. First and foremost, someone could have died. If this is the case, our money is on Father Kieran, who has been slowly deteriorating since a witch placed a hex on him a handful of episodes ago. We’ve seen the results of this hex before in his nephew Sean, and — spoiler — it didn’t end well. Is the coffin in question Father Kieran’s. We could actually see Klaus going to his funeral. Not only does he seem reasonably fond of the former leader of the human faction, but Klaus respects Cami and seems to care about her. We like to think he’d show up at Father Kieran’s funeral if only as a sign of support for the bartender psychologist.

The Originals airs Tuesday nights at 8 p.m. ET on The CW.
