My favorite guest star from the first season of Agents of SHIELD is coming back for a second appearance when the show returns next month. See who it is below.

According to TV Insider Jaime Alexander will return as Lady Sif in the second episode of the back half of the season. But she will have short term amnesia. She remembers that she's Asgardian but not who she's on Earth to stop. Maybe Sif will also be able to shed some light on what's happening with Skye.
