Marvel’s Agents of S.H.I.E.L.D. well full-on Inhuman with this past week’s 2015 premiere “Aftershocks,” but now the Avengers-adjacent series will go Asgardian once more to return Lady Sif (Jaimie Alexander) to the fold. Find out if Sif remembers “Who You Really Are” with the full set of photos and trailer from next Tuesday’s Agents of S.H.I.E.L.D.!

As we learned previously, Sif’s return to Earth will present more than a few problems, as the Asgardian brawler somehow loses memory of her own identity, as well as the very fiend she arrived in Midgard to pursue. Skye’s continue inability to control her quaking powers doesn’t help matters, while it looks like Bobbi and Mack have their own battles to fight with a mysterious intruder to the base.

So says Marvel of next Tuesday’s “Who You Really Are”:

Coulson and team come to the aid of a confused Lady Sif, who has lost her memory after fighting with a mysterious warrior whose true mission will send shockwaves through S.H.I.E.L.D. Meanwhile, Bobbi and MacK continue to hide their true mission from everyone close to them, on “Marvel’s Agents of S.H.I.E.L.D.,” Tuesday, March 10.

Guest starring are Adrianne Palicki as Bobbi Morse, Henry Simmons as Alphonso “Mack” Mackenzie, Jaimie Alexander as Lady Sif, Eddie McClintock as Vin-Tak, Alexandra Manea as nurse, Lidia Porto as head nurse, Danny Lopes as Bruno, Ben Griesse as Tiago, Ruben Rabasa as Mr. Cardozo and Markell Andrew as officer Carvalho.

Still to come of Agents of S.H.I.E.L.D.’s return, we know that Battlestar Galactica vet Edward James Olmos will put in an appearance as the mysterious Robert Gonzales, a man who “will have massive repercussions for Director Coulson and his team,” while Luke Mitchell will portray the Inhuman “Lincoln,” Drea de Matteo will play the villainous Karla Fay Gideon and Blair Underwood guests as Melinda May’s ex-husband. In addition, upcoming Marvel’s Agents of S.H.I.E.L.D. episodes will also begin to lay ground for Avengers: Age of Ultron in some capacity.
