Executive producer Stephen Nathan spoke about "The Change in the Game" after the Bones season finale aired last night. If you haven't seen it, we won't give away any details in this paragraph, but you should probably turn back now.

We don't want to spoil the last 10 minutes for you, because there aren't too many episodes that leave you bawling, then gasping and exclaiming "WHAT!?"

Here are excerpts from Nathan's chat with EW ...

On whether Brennan is for real: "Absolutely. This is not a dream"

On whether this twist was built around Emily Deschanel's real-life situation: "This was something that we had been discussing even before Emily found out she was pregnant."

"It’s very difficult to find a way to deal with two characters who everybody knows should be together without embracing what everybody calls the Moonlighting curse."

"We had to find a way to keep Booth and Brennan Booth and Brennan and keep the integrity of those characters intact, and yet move them along because you can only wait so long."

"So we wanted to avoid that part of the relationship where you first get together and the fresh glow of love, and you’re sharing dessert, and you’re overly polite."

"We didn’t want to do that. Booth and Brennan have disagreed about fundamentally everything - except each other - for six years. That will continue."

"Their characters will remain the same: Booth and Brennan will have completely different ways of dealing with the pregnancy, completely different ways of dealing with where their life goes from here. Booth is the marrying kind as we know, and Brennan is not."

"Where are they gonna live? How are they gonna raise the child? All of these issues will be dealt with in the way that they’re always dealt with - from opposite sides."

"The ultimate pragmatist meets this romantic who has faith that everything will be worked out as long as you look at it the right way."

"These are issues that won’t die. We hopefully have found a way to continue what everyone loves about Bones while really kicking it up a notch and adding a whole new set of complications now that these two people actually find themselves together."

On when Season 7 will pick up: "It’s not gonna be two weeks later. We’ll see them a little bit further along. Exactly how far along remains to be seen."

On the time elapsed between the last two episodes: "Probably at least a month."

On whether B-squared did the deed once or multiple times: "I think that’s up to every viewer. I have my little feeling about it, but I don’t want to impose my opinion on that on anyone."

On their future as a couple: "Well, we’ll now see them as a couple - whatever a couple means to Booth and Brennan. [Laughs] It will be that unique couple. It won’t be what you expect."

On adding a baby to their dynamic: "We want that to affect the show, but it’s not gonna be a show about having babies. It’s not Parenthood. I’m sure there are gonna be viewers who are upset. 'Oh, the baby’s gonna do this and do that.'"

"A lot of viewers always make up their mind on how we’re gonna ruin the show before it happens. [Laughs] And hopefully we will disappoint those viewers. As for the viewers who have faith, we hope we won’t disappoint them. We’re very, very excited."

On how the babies will change the show overall: "Bones is still Bones. We’re still gonna have gruesome murders and find the killer. That’s still always the main thrust of the show. We’ll follow their lives and follow the progression of relationships, but that’s always gonna be the backdrop against killing people."

"The babies will definitely factor in the show. Every week? I can’t imagine. But it will be a part of their lives. We’ve known these people for six years. We’ve seen them grow."

"They have children and their lives progress and evolve, and we’ll see a part of that while we’re, you know, tearing the flesh off of a horrendously decomposed body."
