Sif to Return to Agents of SHIELD

According to a report from TV Insider, Asgardian warrior Lady Sif will be returning in the March 10 episode of Agents of SHIELD. Apparently, Sif will have lost her memory after a battle with an unnamed foe in Portugal. Executive producer Jim Bell said,

Sif has no idea who Thor is or that she serves a king, and we're going to have fun with that. It'll give us some much-needed humor in a season that's been full of betrayal and death. Sif can't even recall who she came here from Asgard to stop, but Agent Coulson and his team will try to help her figure all that out. We've been dealing a lot with space aliens and Inhumans in our last few episodes—things our Earth-bound heroes just don't know much about. They need help understanding what's really going on. Sif's memory—what's left of it—will come in very handy.
