The Lady Sif is making a trip to Midgard, and her journey will lead her straight to our favorite Agents of S.H.I.E.L.D.

That’s right, True Believers, Jaimie Alexander will make a special guest appearance as Sif in an upcoming episode of "Marvel's Agents of S.H.I.E.L.D.," reprising her role from Marvel's "Thor" and "Thor: The Dark World"!

Last seen in "Thor: The Dark World"—now the third largest grossing Marvel Studios film—Sif has come to Earth with a very specific mission. Unfortunately, we can’t tell you just what brings her to our neck of the woods just yet.

Don't miss "Marvel’s Agents of S.H.I.E.L.D."
