Jaimie Alexander will reprise her role as Lady Sif on Agents of SHIELD season 2.
The ABC series returns Tuesday, March 3 and in the second episode back, Sif comes to Earth on an undercover mission and has a bodyslamming showdown with a foe whose superpowers are equal to her own. (Marvel is keeping the baddie's identity hush-hush.) Footage of the epic clash, which takes place on the coast of Portugal, becomes big news on social media, prompting the S.H.I.E.L.D. agents to rush to the scene to investigate. Not only do they find Sif without her lusty trademark armor, but she has also lost her short-term memory.
