In Darkness, His Memory Burns - Episode 4

Keira is held captive and repeatedly called by name while an unseen captor taunts her — "It's the most fun I've had in ages," mocks her struggles and threatens, "I'll kill them," adding, "I hope her fiancé likes her present." The taunting escalates into repeated kill threats as Keira fights. In a separate moment Mr. Potter confirms, "Just like you predicted — Felix has been sent to our sanatorium," and someone answers, "Got it." With Felix sent away and Keira still trapped and threatened, the episode ends with her fate unresolved and danger looming.
