“The central question of season 4 is: Can these women change?

And if so, what is the nature of their change?”

sums upKilling Eveexecutive producer and new head writer Laura Neal.

“We’ve asked that pretty much for every character, and that’s the jumping-off point.

Were these people born or were they made?

And if they were made, is there a way back for them?”

How many wigs, aliases, and international locales will this season offer up?

EW asked Neal to share some key intel on all the kills and thrills to come.

“That sums up Villanelle’s approach to competition in general, but also to religion.

Brace thyself for one of the show’s most surreal sequences during Villanelle’s religious awakening.

“Seeing Villanelle’s effect on Eve outwardly felt really thrilling to me.

That’s not the only wig for Eve.”

“What’s exciting about Eve is that she is cut loose,” says Neal.

“She is done with doing the good thing, and she’s done with doing the right thing.

Her sole focus now is serving her own desires, no matter how twisted.”

In addition to the church, Villanelle also will give a shot to find religion via therapy.

“I would call it the most terrifying therapy session ever for a therapist,” sums up Neal.

“She doesn’t request therapy in a very, um,subtleway.

She demands it in an extremely aggressive threatening way.

Villanelle will go toe to tail with a formidable adversary named Lucifer.

“Villanelle literally takes on Lucifer in episode 1,” says Neal.

“In terms of a cosmic battle, you’re not going to get any bigger than that.”

Season 4 reunites them much earlier than previous seasons did, but the dynamics have metamorphosed.

They know where they are, they can find each other.

But I have this very important thing to do.

You will see Eve’s former boss in paradise and out of her element.

“We find her kind of out to pasture,” reports Neal.

In repayment for that, they’re expecting her not to make any trouble.

And the politics of intelligence leads to strange, dangerous bedfellows.

“Her previous moral code is thrown up in the air,” says Neal.

“She aligns herself with people that were previously enemies.”

Oh, and in potentially related news?

“Carolyn spends more time than we’ve ever seen before with Villanelle.”

Like Carolyn, Konstantin is living the good life.

But unlike Carolyn, he’s enjoying his life, back in Russia.

“We love to the idea of giving Konstantin a bit of luxury,” says Neal.

“We find him finally with an ounce of happiness and with an ounce of true status.

The man with nine lives (and more than nine lives) will question how he has led them.

How has that changed how she reacts to this kind of woman?”

“But it only heats up.”

Not to get too morbid, but death looms over season 4 in unexpected ways.

“We loved the idea of seeing an origin story for an assassin,” says Neal.

“We also loved the idea of somebody who is much more of an underdog than Villanelle.

Does it take more than an affinity for death to become somebody like Villanelle?”

If Villanelle will rock you to death, Eve will rock you…. to sleep?

And what felt really important for the finale was to instill a feeling of glory.

That felt like a key word.

We threw it around a lot when talking about the final episode.

The final episode could be a hundred different things, but it had to be glorious.”
