Last week's mindboggling episode of "Teen Wolf" showed Lydia and Stiles talking to the mysterious but highly intelligent Dr. Valack in order to get information about the Dread Doctors. Valack revealed that the Doctors worship the supernatural, have immense powers including the ability to prolong their life span and erase the memory of anyone who has seen them.

In the season's forthcoming episode six, Scott and his pack finally read the book and start to experience strange things, according to SpoilerTV. All lost memories, especially painful ones, will come back to haunt each member of the pack. Fans are most interested in knowing what happened to Lydia in the operating room while undergoing her surgery.

In an interview with The Hollywood Reporter, executive producer, Jeff Davis, pointed out that reading the book gives Lydia clues as to what may have happened to her. "This episode also points Lydia in the direction of figuring out what happened to her in the operating room during her surgery and whether or not it was actually a memory or something stranger," the creator revealed.

Moreover, this is not the last viewers will see of Dr. Valack. He will play a significant role in the back half of season five. To make matters worse, the once three-eyed creature will take control over Eichen House. Does this have something to do with Lydia giving him her banshee scream record?

Kira and Scott shippers are going to be disappointed to know that she starts to pull away from her boyfriend and her pack. The kitsune is rising in power and cannot seem to keep it under control. Fearing she will harm someone, the Japanese girl will pull away.

Things will get worse for Malia and Stiles thanks to him keeping Donavan's death a secret. Looks like Scott's pack is losing its unity.

Another SpoilerTV report claims that audiences will see a young Scott McCall in "Required Reading" in one flashback sequence where he will be seen having an asthma attack.

"Teen Wolf" airs Mondays at 10 p.m. on MTV.
