Jessebel is Thaddeus and Thor's friend who resembles Isabella, and is considered Isabella's rival. Like Isabella she is the leader of a troop called the Waterfront Girls, however, unlike the Fireside Girls who are friendly and helpful, the Waterfront Girls act like a disciplined and focused army squad. Unlike Isabella who is kind and helpful, Jessebel is rude and competitive, she also has a crush on Thaddeus, but Thaddeus is too egotistic to pay attention to her anyway. She is Matt's sister.
