The Asgardian sorceress Lorelei makes another rapturous entrance in the opening sequence of Agents of S.H.I.E.L.D. season 1, episode 15.

The opening sequence of Agents of S.H.I.E.L.D. season 1, episode 15 has been released on SpoilerTV, demonstrating the dangers of interacting with a magician-goddess from another world. The episode, titled “Yes Men,” will focus on the havoc wreaked by said goddess (Lorelei, played by Elena Satine) when she jaunts down to Midgard for a quick world takeover.

You know, as you do.

In the opening sequence of “Yes Men,” Lorelei amps up the destruction she began in the tag to last week’s episode. She quickly disposes of the poor newlywed she enchanted for a ride out of Death Valley, and recruits a whole team of biker dudes in his place.

Luckily for Earth, Lorelei will soon have a familiar face to deal with in this episode. Much to the delight of Marvel fans, actress Jaimie Alexander will be reprising her role from Thor and Thor: The Dark World as the incomparably badass Lady Sif. Sif will team up with Agent Coulson’s crew in order to take down Lorelei before she can… do whatever bad things she’s popped down to Earth to do.

The official synopsis for Agents of S.H.I.E.L.D. season 1, episode 15 promises that Asgardian politics will be a pertinent factor in the battle between Lorelei and Sif. We can only hope that the incognito presence of Loki up on the Allfather’s throne may also resonate in “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.

As the preview and another sneak peek from Agents of S.H.I.E.L.D. season 1, episode 15 make clear, though, Sif and Team Coulson may have their work cut out for them.

Agents of S.H.I.E.L.D. season 1, episode 15, “Yes Men,” airs tomorrow night at 8:00 p.m. on ABC.
