Ever since the shocking midseason finale of the first Marvel Cinematic Universe tie-in series, audiences have been wondering what exactly goes on with Skye (Chloe Bennet), as she gains new powers - after getting a glimpse of what she can do the last time around, the "Marvel's Agents of SHIELD" season 2 episode 12 will bring audiences closer to the truth.

Over the last episode, it was discovered that Skye, whose real name is Daisy "Quake" Johnson (a Marvel Comics SHIELD superspy who has the power to generate earthquakes), was already developing her powers, but was keeping them quiet because Jemma Simmons (Elizabeth Henstridge) would endanger her if she knew - so, what'll happen in the "Marvel's Agents of SHIELD" season 2 episode 12?

According to International Business Times, the "Marvel's Agents of SHIELD" season 2 episode 12 will bring another Marvel character, from "Thor": Lady Sif, played by Jaimie Alexander, who seemingly lost all her memory upon having a fight with an unnamed warrior, and it's unclear what exactly she's doing on Earth during this particular visit, although it is believed that it has something with destroying the Inhumans, the superhuman race Skye belongs to.

Screen Rant reports that Lady Sif's "Marvel's Agents of SHIELD" season 2 episode 12 mission will definitely "send shockwaves" through the team led by Phil Coulson (Clark Gregg), as she is said to be on the course to reveal further about Skye's nature as an Inhuman.

As it is unknown who was the unnamed warrior that took out Lady Sif's memory, many news outlets have assumed that the "Marvel's Agents of SHIELD" season 2 episode 12 will be a bigger tie-in with the Marvel Cinematic Universe films, most likely with "Thor."

As Yibada reports, another big issue in the episode will be Bobbi and Mack's (Adrianne Palicki and Henry Simmons) secret mission.

You can watch the "Marvel's Agents of SHIELD" season 2 episode 12, entitled "Who You Really Are," on ABC at 9pm EST.
