Penn Badgley digs deep into darkness on ‘You' season 5

Penn Badgley is onto another dark season of his hit crime thriller show, You.

The actor, who plays Joe Goldberg in the series, has dropped the official teaser of the fifth and final season of the show, as he touches upon the past.

The scene opens when Joe’s “happily ever after” is interrupted when “his perfect life is threatened by the ghosts of his past and his own dark desires.”

The trailer begins as Joe speaks: “Hello, you. Do you remember me? Because I remember you.”

“Here we are together again, back to where it began,” Joe says as he recalls his romance with Guinevere Beck (Elizabeth Lail). 

“A lot has happened these many years together, identities, cities, loves, complications,” Joe continues.

“But all that led me here, to now, to where I was always meant to be,” he declares as books appear on the screen. “And the one constant, the one thing that has always been there for me, is you.”

“You, who have been there the whole time, and will be there with me to the end,” he says as the sneak peek at the “killer finale” concludes. “Goodbye, you.”

‘You’ is set to premiere on Netflix on April 4.
