• Between declarations of love, a tragic death, and an evil stepmom, Penelope quit as Lady Whistledown.
• But just as quickly, a new Lady Whistledown stepped up to the challenge.
• Spoilers ahead for season four, part two of "Bridgerton."

Don't worry: The "Bridgerton" writers know who the new Lady Whistledown is. A "Dan is Gossip Girl" situation, this is not.
