Lets do that.'

So what was Tom looking at in the last shot of the finale?

Wyle teases, All Ill say is its not a new alien race that were looking at.

It is something we havent met before, but its familiar.

Is it an alien hybrid?

Is it artificial intelligence?

Is it something with the DNA of a specific character weve met before, like Rebecca?

It is a more emotional, internal motivation that propels Tom Mason in season 5.

The rights for that were a little outside our budget.

So you would hear that and go, Oh my God, thats a friend.

Theres a friend nearby or Theres someone who understands me.

Thats the first moment where we might have some hope about what he might encounter in this environment.

But the specifics are everything, right?

You gotta find the things that really pull those strings.

That went back to even the writers room when we were breaking the story.

Is this creature in the mirror an example of that?

So once you say that theres this race called the Espheni and we determined that their M.O.

is playing with DNA, playing with genetics.

Thats a great fertile soil to plant a whole bunch of things in.

Did this final scene have any influence from the end of2001: A Space Odyssey?

That was definitely not only a conceptual influence, but an aesthetic influence.

It just seemed like the shows always been about family first.

I said when I was initially meeting with everybody about it, Its a family drama writ large.

I just didnt want to see their daughter turn out to be something profoundly evil.

She can make mistakes she even killed somebody.

But in the end, she opts for a choice that serves our larger theme of family.

What happened to Mira, the reeducation camp girl?

Was she still alive on the ship when Lexi flew it into the Espheni power core?

I gotta imagine so.

You didnt really see her except that she sort of scooted away.

She was really one of my favorites in the cast.

It was really hard.

Fans are still waiting to learn why the Espheni really invaded.

Remi and I know each other.

Remi was involved in co-creating Caprica.

So he and I have actually created a show together, and we spend a lot of time together.

I had several conversations with him about the show and about that question.

If if we just said, They need our water, the audience would say, Bullsh.

What other teases can you give us about why fans should be excited for season 5?
