Aria Montgomery (Lucy Hale) managed to keep her illicit relationship with her former teacher Ezra Fitz (Ian Harding) a secret for nearly two seasons on Pretty Little Liars -- until the mysterious "A" forced them to come clean to her parents, that is.
Us Weekly has a sneak peek from Monday's all-new episode, where Aria's father Byron (Chad Lowe) confronts Ezra and threatens to have him arrested if they continue their courtship.
"I want your assurance that this was a mistake and that it's over," a stern Byron says to Ezra. "You are never seeing Aria again. Ever! And I will make sure that the police see to that."
Pretty Little Liars airs Mondays at 8 p.m. EST on ABC Family.
