It could all end tonight. Agent Carter has been a fun ride for the two seasons that have aired , but tonight may be the last time we see Peggy Carter and friends. Thanks to sub-par ratings, it will be a pretty big surprise should ABC actually renew the show for a third season. Star Hayley Atwell is not letting her thoughts and feelings get ahead of any announcement.

She has continued to talk about how season 2 will end tonight and what it could mean for the future. While speaking to The Hollywood Reporter, she was once again asked how season 3 would work alongside her new series. She reiterated old statements but also that ABC made it clear with the offer that they’d make it work.

That’s something ABC has talked about a lot [with me]. If [Conviction and Agent Carter season three] both got picked up, then we’d work out some way where I could do both.

I don’t know the details of how that would work or when it would happen. But they said that in the same sentence when they offered me Conviction which I was very flattered to get. But they also said this doesn’t actually mean anything yet for Agent Carter. So we’re just out in limbo in that respect. All I can do at the moment is just focus on the pilot that I have to start filming two weeks from now and do the best that I can with that. And then I’ll just see what happens and see how people respond to it.

Tonight’s finale will wrap up the story of Whitney Frost and Peggy’s adventures in Los Angeles but also tease things for the future. Last year’s finale left us with questions of Dottie’s location and a cameo of Arnim Zola. Atwell is happy with the ending and what stories could be told in the next season.

I’m really satisfied with where it ends and what happens to Peggy. I’m proud of this season. So if we get the opportunity to work on it again, then brilliant. Because then I’m sure I’ll have even more fun working on it than I did in season two which was a lot. I don’t quite know how to top that. But I’d love the opportunity to try. … The writers have very elegantly put together this ending. I definitely want more.

Season 2 has had a lot of moving parts, returning characters, and new ones that could make it tough to wrap everything up nicely in a single hour. Atwell assures that will not be the case and that we will be pleased with how it wraps up.

There’s a balance with how it ends. There’s enough of a cliffhanger to suggest that that’s where we’ll go forward if the show gets picked up again. But things are nicely wrapped up in a way that I think the audience will find very satisfying. The audience won’t feel frustrated. If anything, they’ll come away satisfied but also curious as to what happens beyond, because thanks to all the Marvel films she has appeared in, we know that Peggy’s life goes on and she lives quite an extraordinary life and a long life. So there’s always room to revisit her in different ways, different decades and different ages.

Peggy was initially sent to LA as a joke from Thompson to make Sousa’s life more difficult and awkward. They had a clear spark in season 1 that had a falling out between the seasons. That romantic interest has started up again, but Atwell doesn’t know if they end up together.

I don’t actually know if she ends up marrying him, because I think it was said somewhere that she ended up marrying someone that Captain America had saved at one point. I think she said that in Captain America: The Winter Soldier, so I don’t know what they’ve got in mind for that really. So if Sousa and Peggy were to get together, that doesn’t exactly mean they’ll be together forever. It could really go either way.

They’ve been through quite a lot together so their relationship could really be summed up into bad timing. It will wrap up in this season in quite a satisfying way for the audience in one way or another. I would say there is a conclusion that they come to. I know that they both have been quite frustrated and quite tired with how the situation has unfolded so far so it’s nice that they’re going to get the chance to finally come to some kind of resolution.

Everybody has those people or couples that they look to and aspire to be like. This season has given us an inside look at Edwin and Ana Jarvis’ marriage, and oddly enough, Peggy is striving to be more like Jarvis in this aspect.

Peggy never truly realized the strength it takes to live through what Jarvis [James D’Arcy] lives through and deals with it how he does. She really has a newfound respect for him after this season. And with Jarvis and Ana [Lotte Verbeek], she now has this mature, beautiful relationship in front of her that she can aspire to one day. She loves what she sees between them and she finds it very inspiring.

Atwell also talked to IGN about this season, but started off talking about tonight’s episode. At the end of last week, there were different standoffs that did not look like they would end well for all parties involved. Even though she strangely does not watch her own show and seen the episode, she says it should be very exciting.

It’s quite a game of human chess, isn’t it? I’m not sure where it picks up, because I haven’t actually seen the episode! I don’t know, because I don’t watch the show. I don’t watch television. [Laughs] I know that sounds really strange, but I don’t. I’m a real nerd and I read books instead. So I don’t know how they edited it, and when we were filming, we were kind of doubling up lots of different scenes at the same time. But it does reach an evolution, that’s for sure. Some sound — a big bang — goes off and some people get out of there okay

One of the complains viewers have had about this season is the use of Jack Thompson and the lack of (or even dwindling) development of the character. If you do not like him, you are not alone! Atwell thinks that Peggy feels the same way.

I think she’s so fed up with him. I am! [Laughs] I think Peggy’s got a lot of patience, more patience than I have, and she likes to see the best in people and give them the benefit of the doubt, so she’s probably doing that, to an extent, with Thompson. But in this situation, as it presents herself, she’s not going to put Thompson in front of saving the world. I think she knows what her decision would be if it came to it. But at the same time, she has a history with Thompson and she knows the kind of guy she’s dealing with and underneath the bravado, there’s a scared little boy who wants recognition because he doesn’t have the same self-esteem that Peggy has about herself. And I think that makes him kind of… She can kind of be endeared to him for that reason and that allows her to tolerate him, I suppose.

Howard Stark (Dominic Cooper) will also be making his return tonight. Even as a side character, he has been there for some of the bigger moments of the series so his role tonight should be fun to watch. Atwell talked about the character and his relationship with Peggy.

Well, he’s wonderful. He’s like a fairy godmother. He turns up at these important points, like this last episode. When they’re together it’s the three musketeers. Howard and Peggy and Jarvis are essentially the core of that team; the good guys. Howard’s relationship with Peggy develops from one of experiencing betrayal from Season 1 to just understanding that he’s human and going to do things she doesn’t agree with – his womanizing being one of them and his spending being another. However, underneath that, she’s invaluable to him and he’s invaluable to her and that’s just nicely demonstrated in the finale.

Finally, following tonight’s episode there will be plenty of questions about the future. Unfortunately, ABC is notorious for holding out on these announcements, with Atwell reiterating the wait her, the crew, and us fans will have for any sort of season 3 renewal or cancellation.

I am hearing at this point that we don’t know anything and we won’t know until the Upfronts in May.

The season 2 finale of Agent Carter airs tonight at 9 p.m. EST on ABC.
