If you are a fan of the Thor movie franchise, you might recognize the name Jaimie Alexander. She is the actor who played Lady Sif in the films. In her turn on the TV show, she will reprise her role as Lady Sif and will be trying to bring an evil Asgardian back home for justice reports Entertainment Weekly.
The Asgardian that she is trying to collect is Lorelei played by Elena Santine. Lorelei has been in an episode of the the series already as she tries to wreak the world. I'm more than a little behind in this show, but my trusty DVR is holding all the episodes for me.
The show got a little tedious and I stopped watching it. I’d like to see more superheroes turn up in the show, I think that would make it more enjoyable. This would be a good place for for some of the lesser superheroes to turn up in that aren’t likely to see their own series or movies.
Her stint on the TV show will shed a bit more light on Sif and her charms. Alexander said, "You definitely see a lot more of her and how she interacts with other people. Essentially, she comes to earth hunting Lorelei. She’s been sent on a mission to bring Lorelei back to Asgard. And so with that, she’s in someone else’s world, on their turf, and she enlists the help of S.H.I.E.L.D. out of respect. I think she’s definitely a one-woman army when it comes to doing things, but she’s also respectful of other territory and she knows she can trust S.H.I.E.L.D. because Thor [Chris Hemsworth] did. And that speaks very highly to her. So the crossover in general is such a great thing. It’s been awhile since she’s been on earth."
