WARNING: The following contains minor spoilers for The 100 Season 7, Episode 2, which aired Wednesday on The CW.

Marie Avgeropoulos has starred as fan-favorite character Octavia Blake since the 2014 premiere of The 100. While the entire cast has experienced an emotional roller coaster of post-apocalyptic shock and awe throughout The CW series' seven-season run, Octavia in particular has endured a turbulent character arc. From her origin as an outcast trying to rebuild civilization on a devastated Earth, Octavia grew into the battle-hardened Red Queen, ruling a bunker full of survivors with a bloody fist in Season 5.

In Season 6, Octavia began to explore the possibility of redemption as the characters traveled to the faraway world of Sanctum after Earth became completely uninhabitable. The season ended with a young woman named Hope sending Octavia through the temporal anomaly, a phenomenon that bends the laws of space and time. In an interview with CBR, Avgeropoulos reflected on her time portraying Octavia, and what to expect as the seventh and final season continues.

CBR: With Octavia in this second episode of Season 7, we're maybe seeing her the happiest she's been since the start of the series. How was it to make that change?

Marie Avgeropoulous: It's been really exciting to make that change because Octavia on Skyring has become a stepmom -- even though Hope calls her Auntie O, it's really a two moms [dynamic] -- to co-parent this beautiful child we now know as Hope. And it's a very isolated planet and all we can do is garden and sit around with our thoughts and parent. It's kind of what a lot of people at home, especially those that are working from home, are doing right now. So I guess it's serendipitous, in a way.

The past two seasons, your character has really been put through the wringer. Was the change in becoming a co-parent to Hope and a farmer, but still a badass farmer, a refreshing change for you?

Yeah, I think all moms are badass and it's cool that Octavia has to have the refreshing experience, again to metamorphosize into a parenting role. She had to make a lot of sacrifices and, also while in isolation to parallel the [real world], Octavia is left with her thoughts and learning the parenting skills that were taught to her through [her brother] Bellamy. As we saw in Episode 2, Octavia becoming a midwife and helping Diyoza deliver her beautiful baby Hope, and to soothe and shush the baby, she put her pinky in baby Hope's mouth. That was a great throwback to what happened when baby Octavia was born under the one-child rule on the Ark way back when and Bellamy managed to shush her doing the exact same thing.

I think Octavia's time on Skyring really gave her time to sit with her thoughts and realize Bellamy deserves a lot of apologies and thanks, ultimately, to rekindle their sibling relationship versus the sibling rivalry that we've always known throughout the seasons.

I feel like the emotional core for all seven seasons has been your character's relationship with her brother. I was wondering if you could tease if we'll get a payoff to that and how it's been working with [co-star] Bob Morley for the past seven years?

It's been so fun working with Bob Morley for the past seven years and it did make sense because he's a couple years older than me and he had more acting experience than I did. So he really did mentor me throughout the years and, even though our storylines were often quite dark, in between the takes, we always managed to laugh and joke and be supportive to one another. And if I ever had questions about choices I wasn't so sure about, there was never any ego, he was always open for me to chat about it so I always felt comfortable.

So, in saying that, I always looked up to him, and due to COVID-19, of course, we didn't get a proper goodbye. There was no wrap party. We abruptly said "Sayonara" to one another but, that being said, he always made me feel comfortable and he was the best fake brother a girl could ever ask for. [Laughs]

There really have been a lot of intense moments, it's been an emotional rollercoaster ride. Were there many moments or directions that made you raise your eyebrow a bit?

No, I've always trusted [the writers], honestly. I've never asked for any news about Octavia because I've always taken it one script at a time, one page at a time and one story at a time, because I've always wanted to shock the viewers. But I've only learned how to shock the viewers because the writers shock me first. I never had a clue where Octavia was going and I think that's what helped me metamorphosize her character throughout all of the seasons. Ultimately, what I've been hearing over and over, that's what the fans love about her so much; she's incredibly unpredictable.

The most intense season I've seen was Season 5 with Wonkru, institutionalized cannibalism and you as the Red Queen. How was it bringing that level of intensity, day in and day out?

That was a pretty dark place for me for awhile. It was, of course, based on the gladiator pits in Roman times and, to honor the writers, a lot of this was based on things that have already happened in history. But to play the Red Queen, Bloodreina, she was really focused on believing her own negative bullshit. I'm Canadian and can't vote in America but it does remind me of somebody that's in power right now over there. [Laughs] As an actress, I was supposed to believe my own sort of negative storyline to make everyone follow my rule. And, unless everyone does what I want them to do, then everything in the bunker would've gone sideways to have so many different plans and so many different beliefs and support systems and political opinions work underground for six years straight.

It's kind of similar to things that are happening now and it's definitely relevant to things that have happened in the past. But, again, the cast that I work with is so great that, in between takes, we would always laugh because you can't just sit in the headspace of cannibalism all day long and expect to go home not raising your eyebrows and feeling upset on a day-to-day basis. I think that Octavia smiles once in 100 episodes. [Laughs] But that makes it so much more interesting. The world was always a twisted, wonderful one to watch.

You've been portraying this character for the better part of a decade now. What are some of the things you're proudest of and, looking back, what does the character mean to you? How does she still resonate?

I think the thing the most proud of I am about playing Octavia is she always stares fear with two eyes but uses bravery instead. I think she's really good at being brave and hiding the fact that she has no idea what she's doing. But, at the end of the day, she puts worry and anxiety aside and treks forward knowing it will work out because Octavia has always jumped into whatever challenge that's in front of her with two feet. And that's something that I feel like I do in my life as well, and something that all of us are doing right now, whatever it means in your day-to-day routine and certainly what it means in mine.

And, right now, that just means everything's going to be okay. I will get to tell stories again on movie sets one day. Maybe it'll be different, but right now, I'm going to plant my garden in my backyard and watch the onions come up, and that's okay too.

To close us out, Marie, what can you tease about Octavia's arc in this final season?

I'm really excited for people to see this show -- I'm sure they've already started watching it because everyone's watched everything there is possibly to watch on Netflix -- but if I could describe Octavia in Season 7 in three words, it would be self-actualized, nurturing and elevated. For the rest, they'll have to tune in.

The 100 stars Eliza Taylor, Marie Avgeropoulos, Bob Morley, Lindsey Morgan, Richard Harmon, Tasya Teles and Shannon Kook. The series airs on Wednesdays at 8 p.m. ET/PT on The CW.
