From curious Carrie to costumed Carrie, The Carrie Diaries will celebrate Halloween next Monday night.

On "Fright Night," Larissa will invite Carrie to a New York City party in honor of the holiday, as she brings Walt along with her for company.

What role will LSD play during the hour? Where will Maggie and Mouse end up? What shock is in store for Doritt when it comes to her father? All good questions, all of which will be answered in six days.

In the meantime, check out the following CW trailer for The Carrie Diaries Season 1, Episode 4:
