Get a Sneak Peek at Jaimie Alexander as Lady Sif on ‘Agents of S.H.I.E.L.D.’

While television ratings for Marvel’s Agents of SH.I.E.L.D. have pretty much evened out, but ABC is looking to create a spike in viewership on March 11 when Jaimie Alexander guest stars as Lady Sif.

Sif is the first character from the Marvel Cinematic Universe to crossover to the television series (not counting Stan Lee’s blink-or-you-miss-it cameo a few weeks ago). We’ll leave out the spoiler-y plot details but tune in to watch Sif fight a supervillain sorceress.

Until then, check out a new batch of promotional stills from the episode.

Are you still watching AoS? Will you tune in to watch Alexander throw down on the small screen?
