Forget what you think you know, Originals fans, because Episode 5 (“Sinners and Saints”) is about to throw us for a loop — especially when it comes to Davina and Sophie.

“Everything you believe is wrong,” tweeted writer Michael Narducci, along with a photo of the two witches.

We know Sophie reveals a “troubling secret from her past” to Klaus and Rebekah in Episode 5. We’re starting to think Sophie’s secret has something to do with the “shocking information” Davina tells Elijah in the same episode. According to the synopsis, it will lead to a “disturbing revelation” — but about whom? Will this revelation have something to do with the witches, Davina, or Marcel?

Perhaps the witches were trying to find a way to rid the world of vampires? Maybe they were using Davina’s magic to do so? After all, it’s not like these two supernatural lineages have the best history. Also, how will this shocking revelation affect the alliance between the witches and The Originals?

Is it possible Sophie isn’t as innocent in all of this as we thought? If Marcel saved Davina from the witches, then it would explain why she’s so loyal to him — and why she seems to hate the witches.

What do you think, Originals fans? Is Davina actually innocent in all of this? What do you think Sophie is hiding? Sound off in the comments!

Catch the next episode of The Originals on Tuesday, October 29, 2013, at 8 p.m. ET on The CW, followed by Supernatural.
