It seems the Mark of Cain is the gift that just keeps on giving. Last season on Supernatural, it turned Dean into a demon, and now, its removal has hand-delivered the biggest evil the show has ever seen. (No offense, Lucifer.)

But the real question isn’t what the Darkness can do. It’s what Dean can (or can’t) do to it. What is this “bond” that Dean shares with the Darkness, and what will it mean for the eldest Winchester? “Obviously there is some odd connection,” Jensen Ackles tells EW. “Opportunities are going to present themselves to Dean and this is where we see he’s unable to act in a way that we would normally think Dean would act. There’s this odd hold that the Darkness has over him and he doesn’t know A) What is it; B) How to deal with it; and C) Whether it’s going to get worse or better.”

And of course, because these Winchesters seem to love secrets, Ackles adds, “Dean doesn’t know how to deal with it, nor is he going to tell his brother about it.”

But Sam has his own problems to worry about, namely his recent visions. “The [Winchesters are] in way over their heads, and Sam is obviously really wigged out by these visions,” Jared Padalecki says. “They’re kind of overtaking his psyche because he wants to be committed to finding the Darkness, [and] he’s fairly certain it has something to do with what his visions are suggesting, so that’s sort of their only lead.”

And if Sam’s visions are their lead on the Darkness, you know what that means: “They’re going to start exploring what [the visions] might mean and who they might be coming from.”

I’ve said it before and I’ll say it again: Please be God.

Supernatural airs Wednesdays at 9 p.m. ET on The CW.
