ENTERTAINMENT WEEKLY:Lets start right with the biggest moment from the episode.

Why do that to poor Veera?

GRAEME MANSON:Because nobody is safe on the show and were in our final season.

Youre right, we dont kill clones easily, but I guess it was just M.K.s time.

JOHN FAWCETT:It was.

This was a conflict between the two.

You know, if Sarah and S wouldnt have intervened, Ferdinand would have been dead.

So that should play out interestingly.

Yeah, hes clearly working through some issues, right?

I mean, when you see him stomping hes practically frothing at the mouth.

FAWCETT:Yeah, absolutely.

There was a lot of direction.

MANSON:Johns direction was, Okay, now froth at the mouth.

FAWCETT:There was a lot of anger.

MANSON:Yeah, hes been spiritually betrayed by Rachel.

His heart is a little bit broken so he breaks poor M.K.s heart.

There are many layers and I like it because its complex.

Its not just killing M.K.

EW: Speaking of complex, John,you have this incredibly long scene between Sarah and M.K.

What was shooting that like?

FAWCETT:It was technically extremely complex.

Wed never done anything like that before.

Wed always talked about it but never done it.

So it became this challenge.

I mean, initially, this whole sequence appeared in the season 4 finale.

But wed always been talking about doing one long shot that didnt have any cuts in it.

John wanted to run on rooftops.

We were going to do all kinds of stuff.

FAWCETT:The shot was actually quite a bit more elaborate.

So we realized that we actually didnt have the screen time to manage it.

We have to figure out how they switch clothes and wigs and all that stuff in one shot.

So it was a fun challenge.

EW:What are we to make of the fact that Kira can somehow feel that M.K.

MANSON:Well, its a quality in Kira that weve been lightly hinting at the whole series.

This is perhaps the most human part of Kira.

Its the invisible things that connect us, like extrasensory perception and things like that.

Rachel might get the biology but she wont get this, this feeling, this thing that protects us.

FAWCETT:It was important to us too.

How does Sarah even digest something like that, that her daughter wants to be with her tormentor?

In a show thats often about choice, this kid is standing up and demanding her own terrain.

EW: In other news, we finally meet the mysterious P.T.

Westmoreland who says he wants Cosima to keep working to save herself and her sisters.

How much should we trust this guy?

FAWCETT:How much?

I dont know why on Gods green earth you would trust this guy.

I think there is something alluring about him for certain.
