What can you tease about what Mary’s doing in the season 4 premiere?

ADELAIDE KANE:We left on such on such an ominous note on the cliff side.

It was freezing that day and snowing completely unexpectedly.

So we come in and Mary vows to get revenge for Lola’s death.

That becomes a very important mystery for our first episode.

And she’s going to get two husbands in this one season, Lord Darnley and Bothwell.

And they have to overcome those trials and tribulations during their courtship.

Lord Bothwell really is a classic rogue with a heart of gold.

Bothwell becomes a rock that she learns to lean on.

With Lord Darnley, it seems like in real life they had an unhappy marriage.

Is that going to be reflected inReignor are you going to take liberties and make it happier?

In the last episode of season 3, what’s going on with Leith was left ambiguous.

It looked like he might have died but also he might not have died.

Can you tease anything about what’s going on with him?

Claude definitely becomes very obsessed and caught up in the notion that perhaps Leith might still be alive.

What other shockers can we expect?

I will say Greer survives.

She doesn’t get her head cut off.

We’re not killing off my last lady, thankfully.

She’s the last one standing, brave Greer, through it all.

So they wrote us two different endings just to be safe, a season finale and a series finale.

I think they did a really incredible job.

Ending the show was very bittersweet.

Four years of my life, it’s the most formative job of my career thus far.

And we really had quite a tight-knit family by the time we wrapped up.

Half of them are coming out to L.A.

There are friendships that we formed during the shooting of that show that will last a lifetime.

We were really lucky.

Do you have a personal favorite moment of season 4?

I really love babies and I get to hold a baby.

I get to play with a baby on set.

That’s definitely my favorite part of season 4 was getting to work with a baby.

I definitely don’t want them for another decade but I’m obsessed with children.

All my cousins are having babies.
