Penn Badgley says 'goodbye' in teaser for 'You' final season: Watch here

By Carson Blackwelder

Penn Badgley is upping the creep factor in a new teaser for the fifth and final season of "You."

The clip, released Jan. 30, sees Badgley's Joe Goldberg in a plexiglass prison, making direct eye contact with the camera and seemingly trying to find a way to escape while a voiceover sends shivers down your spine.

"Hello, you. Haven't we met? I'm sure we must have crossed paths. Perhaps I can refresh your memory. I'm Joe. Let's get to know each other better before we bid one last farewell. Goodbye, you," he says.

An official logline for season 5 reveals that Joe "returns to New York to enjoy his happily ever after… until his perfect life is threatened by the ghosts of his past and his own dark desires."
