Actress Jaime Alexander, famous for her role in "Always Sunny in Philadelphia" (and the Thor films, I guess) had a sit down with the LA Times Hero Complex to talk about her role as the female warrior Sif in the upcoming "Thor: Ragnarok." During the chit-chat however, she mentioned how the third installment into the Thor series would have several easter eggs that would be felt throughout other Marvel products."Marvel, I think on purpose, they don’t tell me certain things because they know I’ll be like, 'So here's what's gonna happen.' But I do know I will be in Thor 3 and that Sif will have a very pivotal part in that movie.
