Tuesday's episode of "Agents of S.H.I.E.L.D." will feature Thor warrior Lady Sif's return, according to EOnline.

Lady Sif might appear a little different when she reunites with the S.H.I.E.L.D. team. Actually, she might not even remember her own identity this time.

The reason why Lady Sif ends up losing her memory is due to a fight with a "mysterious warrior."

Coulson and his team come to her aid, and they quickly realize her presence with the team is more important than they thought.

It turns out that Lady Sif knows what happened to Skye and Raina that led them to turn into inhumans.

At first, the team thinks that only Raina was transformed, but Lady Sif convinces Skye she was transformed as well. This leads to Skye's anixety-triggered earthquake powers to come about.

In the trailer for Tuesday's episode, Skye is being questioned by the team about Raina's transformation. They ask her several questions, but she is unable to answer anything. All of these questions make her extremely nervous, and an earthquake is triggered.

One of the team members asks her, "Skye do you want to talk to us?"

Another asks, "Skye, what's doing this?"

That is where the trailer ends. It appears Skye has indeed been transformed, and she is trying to keep it a secret. But with the earthquake ability, she might not be able to keep it a secret for long.

In another clip, Lady Sif emerges out of the water and approaches a group of campers near a bonfire. She says, "I must find Carver."

The campers are confused, and Lady Sif walks away on the beach. One camper decides to chase after her, saying he will help her. She hits him in the chest so hard that he flies across the beach.
