Revolution is firing on all cylinders, balancing morally-complex human drama with huge action-packed set pieces. And — surprise, surprise — the show actually answers its own mysteries at a brisk clip. For example, the cause of the blackout was revealed two episodes ago instead of two seasons hence! (FYI, the military released microscopic machines designed to absorb electricity, and the machines replicated out of control.)

The show returns tonight with an installment titled "The Night the Lights Went Out in Georgia" — the first in an uninterrupted run of seven episodes as the season accelerates to the finish.

David Rambo, a screenwriter and playwright serving as co-executive producer on the show, chatted to Wetpaint Entertainment about what the rest of the season holds in store for our band of rebels as they battle forces vying for power, so to speak.

On the cause of the blackout: "When we first started devising why the lights went out, we brought physicists and strategic planners in — to run all of our theories by them. And they said, 'Oh, yeah, absolutely. That could definitely happen.' But what was really funny was hearing what they thought before they told them, and we thought, 'Well, we might want to change our mind.' But they always thought we had the right idea. That's [show creator] Eric Kripke, who's amazing. Credit to Kripke."

On the continuing fallout of Danny's death: "The first half of the season was 'Get Danny.' The second half is 'Get Monroe.' We are after Monroe. He is going to pay for this. We want him to pay for this. How do we get him? How do we stop this from happening to another kid? So it really galvanized what our characters would be doing ... The most important thing about Danny's death is that capsule that Rachel removed from his leg ... What is that? That's a mystery we're gonna explore."

On the mysterious Grace: "We're gonna see a lot of Grace, in and out. She's very important... I can't reveal too much, but we've not seen the last of her."

On the characters' travels: "We always accurately figure it out. We track it by days, whether they're on horseback, on foot, steam train... We haven't had much with boats yet, but i think boats will play a part. There has to be boat travel in the world...

On seeing different parts of the Revolution world: "We actually see more of North America, which I think is really cool. We will see what the Plains Nation looks like, and we'll see some of Georgia Federation ... I will tell you that we get to see a little bit of the international world later this season, and that is fun. That is really fun. Revolution International!"

On J.J. Abrams, an executive producer on the show: "He's a really good guy. He's brilliant. Ideas just pop, pop, pop, pop, rapid fire... he's amazing."

On his favorite character: "Which of your children do you love the most? I love all of them. For me, I think it's Monroe. Everyone loves writing for Giancarlo [Esposito], for [his character] Neville. Who wouldn't? I think it's Monroe. He's so tortured and so hollow. His moral compass went caterwonkers long ago. And we're always laughing about Monroe and Miles being the hottest couple on TV."

On the season finale, scheduled to air June 3: "I can promise you: It is awesome. No one will see it coming. You think you know what's gonna happen, maybe that happens but then— [mock-gasps]. I remember when Kripke came into my office to tell me about it, it just blew me away. Blew me away."

Revolution airs Mondays at 10 p.m. ET. on NBC.
