After all, executive producer Greg Plageman tells EW they always approached season 5 as a potential series end.

With the reduced order [of episodes], we saw the writing on the wall, he says.

We knew that we would have to approach this season as though it could be our last.

Is it still an all-out war between those who support the Machine and those behind Samaritan?

JONATHAN NOLAN:Thats been the story for the last couple of seasons.

Once you create an all-knowing, all-seeing artificial super intelligence, its not an easy opponent to defeat.

Youll see Harold listening to Root a lot more this season.

If the Machine is resuscitated, will she still be the Machine weve come to know?

NOLAN:Thats one of the other questions of the season.

This season, what are some of the news or real-life issues youll be hitting?

NOLAN:Just to jump in quickly, being inspired by real life events is something other shows do.

Our showpredictedreal-life events [laughs].

Its propaganda to make you do something.

Will Samaritan become even more powerful this season?

PLAGEMAN:Samaritan definitely is growing in its power.

We also have to talk about Shaw.

NOLAN:Nowhere good.

Shaws story has always been a bit of a dark one.

Shes a great character to write, and this season, her reintroduction starts in episode 4.

I wont say much about it, but its one of the best episodes this season.

Inthe trailer, theres a shot of a juicy encounter between Shaw and Root.

Is it safe to say that things will move forward with their relationship?

This is the concentrated version [of the show] now, and there are episodes twice a week.

I think our fans may need to put on their seat belts.
