This past week's 'Agents of S.H.I.E.L.D.' installment, "T.A.H.I.T.I.," teased an Asgardian arrival in its final moments, but next week's "Yes Men" will bring quite possibly our favorite of all. Check out Jaimie Alexander arriving to Earth as 'Thor' character Lady Sif in a new sneak peek from 'Agents of S.H.I.E.L.D.''s "Yes Men"!

Our latest preview of next week's Marvel-ous 'Agents of S.H.I.E.L.D.' installment sees the team tracking an imminent Asgardian arrival, even as Ward and Melinda May worry about Coulson's continued secrecy in the wake of Skye's miraculous recovery last week. Who should descend from the heavens then, but Lady Sif herself, warning us of great danger in our midst!

In all seriousness, it's the most Marvel moment we've seen from the series to date, and it's an especially nice touch that S.H.I.E.L.D. doesn't actually know her identity, but can at least deduce Sif's allegiance from her presence with Thor in New Mexico. Meanwhile, here's what ABC had to say of next Tuesday's "Yes Men":

When Coulson and his team are attacked by Lorelei — a deadly seductress who escaped from Asgard — Thor’s Lady Sif, her longtime nemesis, steps in to try to save them.

Guest starring are Jaimie Alexander as Lady Sif; Elena Satine as Lorelei; Maximiliano Hernandez as Agent Sitwell; Dylan Bruno as Rooster; Alicia Lagano as Rosie; Allan Graf as Sheriff; Rob Belushi as Jimmy.

"Yes Men" will no doubt prove the most exciting 'Agents of S.H.I.E.L.D.' installment to date, but what do you think? Will our first major Marvel character from the movies live up to her cinematic portrayal? Watch the sneak peek from "Yes Men" above, check out photos from the hour below, and tell us what you want to see in the comments!
