According to Marvel.com, the great female warrior of Asgard, Lady Sif will appear in an upcoming episode of Agents of S.H.I.E.L.D. Jaimie Alexander will reprise her role as Lady Sif for this guest appearance. Marvel is not revealing why Lady Sif will cross the rainbow bridge to Midgard and her important mission.
I am really beginning to enjoy Agents of S.H.I.E.L.D. and the way it is universe building for television. They are tightly keeping the continuity with the movie universe.
