Jaimie Alexander is one of the few actors from the Marvel films to make their way over to Agents of S.H.I.E.L.D. In season one, she appeared as Lady Sif in the episode titled “Yes Men”. In that episode, Lady Sif arrived on Earth to retrieve an escaped Asgardian prisoner named Lorelei (portrayed by Elena Satine).

In tomorrow night’s episode of Agents of S.H.I.E.L.D., which will see the return of Lady Sif, we will see a different side to the character as she struggles to remember who she is.

IGN had a chance to talk to Jaimie Alexander recently about Agents of S.H.I.E.L.D. as well as the state of Asgard at the end of Thor: The Dark World. Here are a few snippets of that interview:

IGN: What was it like coming back to SHIELD as Sif, but then having her not know anyone?

Jaime Alexander: It was very comical actually. Definitely comical in the beginning. You know, I was just so happy to come back. I always enjoy playing Sif but I also love working with everyone over at Agents of SHIELD, cast and crew. Just everyone. They’re just great people. And they have such a good time doing what they’re doing. It’s not work for them, which is so wonderful. It’s play. They love to play. They play pranks on each other and do all sorts of funny things. It was just a great experience the first time that, you know, when they called and asked me to do it again, I said “Yeah, let’s just do it. Let’s have fun with it.” Especially this time around, because Sif has amnesia. So there are some very funny moments. But there are also some sadder moments later on when she doesn’t remember some things that Coulson was hoping she’d remember.

IGN: I’m assuming Sif get things sorted out in her head at some point, right? Do we get to learn anything about the state of Asgard? Thor 3’s not coming until 2017, and we left things really hanging with Loki.

Alexander: She does find out yes. With the help of the SHIELD team, she is able to regain some knowledge that she she had lost previously. And there are big questions that are answered on the show that the fans will be quite happy about. But the bigger questions are still lurking. With regards to the end of Thor 2 and how things left off in Asgard. And what’s going on there. Is Loki really Odin or is Odin now Loki, or was it all an illusion? None of that’s addressed in this episode. And to be quite frank I don’t know the answer to that anyway. They don’t tell us. But you do get a lot of SHIELD-related answers in this episode.

IGN: From the previews, it looks like Sif’s going after Skye at some point. Is that all due to her amnesia? What can you tell us there?

Alexander: It’s hard to talk about that because I don’t want to give stuff away, but there are things going on internally at SHIELD that Sif is not aware of. So there’s just this chaotic mess and mixup where everyone’s trying to help each other out. And they’re all these strange pieces of this puzzle, and so when they all get together things start to make more sense. And they start to figure things out and finally work together as a team. And that’s always great to see. Those crossovers between the films and the TV show. So it was all really cool to be a part of again.
