“Marvel’s Agents of S.H.I.E.L.D.” Season 2, episode 12 will show Skye (Chloe Bennet) trying to hide her newfound powers. Luckily, her team will be too distracted with another powerful being. As previously reported, the episode will bring back Lady Sif (Jaimie Alexander) from “Thor.” And according to the episode synopsis, she won’t be the warrior audiences saw in Season 1.

Coulson (Clark Gregg) will meet up with Lady Sif only to discover that she doesn’t remember him -- or anything else. The Asgardian “has lost her memory after fighting with a mysterious warrior,” the synopsis teases. While no hints about this “mysterious warrior” are given, Sif will cause more trouble when the team finds out why she is on Earth.

Sif’s “true mission will send shock waves through S.H.I.E.L.D.,” according to the episode description for "Who You Really Are." Is Sif coming after Skye? In the pictures below, it looks like May (Ming-Na Wen) is trying to help Skye run from someone. Sif may have been sent down to kill Inhumans, but she wouldn’t be the only one who has a problem with humans baring alien powers. Elizabeth Henstridge, who plays Jemma, revealed that Simmons would take out Skye if she needed to.

Meanwhile, Bobbi (Adrianne Palicki) and Mac (Henry Simmons) will still “hide their true mission from everyone close to them.” Last week, they revealed that they knew Fury’s (Samuel L. Jackson) toolbox was in Coulson’s office. Will they break in to get it?
