According to teenwolfnews.com, the mystery of the returning Teen Wolf cast member is solved in the six minute clip released by MTV Monday.
Lydia, showing newly mastered ninja skills an some sort of super scream, manages to escape the confines of Eichen House only to be confronted by the ghost of her werewolf ex-lover Aiden (played by Max Carver) who tells her she has to go back to the gentle mercies of the mental ward.
We still don’t know if this is the only returning cast member. It seems Lydia’s Banshee abilities allow her to now see as well as hear the dead which opens the door for any number of deceased cast members to return.
The six minute clip was released first to eonline.com but quickly spread to other sources.
Teen Wolf Season 5 debuts on Monday, June 29 at 10pm on MTV. On Tuesday, June 30 at 9pm MTV will air the second episode of Season 5 followed by the debut of SCREAM at 10pm.
