Carly Klapp

Carly Klapp was a hidden villainess from Season Two of Quantico.

She was played by Paige Patterson.

Carly Klapp first appeared in the episode, "Cleopatra," and met Sebastian Chen during the episode's timeline at The Farm. She became a CIA agent later on, and eventually married Sebastian.

In episode 2.12, "FALLENORACLE," it was revealed that Carly went rogue and joined the villainous Citizens Liberation Front, using her marriage to Sebastian as a cover, which also included a phony backstory of being a Senator's aide. Carly's heel turn came when she held Harry Doyle at gunpoint, using the gun she stole from Alex Parrish. After the reveal, the evil Carly demanded that Will Olsen, who has knowledge of the terrorists' identities, be turned over, threatening Harry's life while accusing Alex of being exactly like she is.

Sebastian was taken aback by his wife's reveal, but still pointed his own gun at her, while attempting to talk her down. Despite Carly's claims that she loved Sebastian, the villainess fired a shot at Sebastian, who still managed to shoot Carly in her head, killing her.
