Lady Sif (Jaimie Alexander) makes her second appearance on Agents of S.H.I.E.L.D. This time around, it's Coulson and company that have to come to her aid when she loses her memory fighting a mysterious warrior.
Bobbi and Mack hide their real mission from the rest of the team on Marvel's Agents of S.H.I.E.L.D. "Who You Really Are" is the 12th episode of the show's second season.
Looks like Brigadier General Glenn Talbot (guest star Adrian Pasdar) is still playing nice with S.H.I.E.L.D., but will it last? Tune in March 3 at 9/8c to find out.
