Although a reprehensible figure in many ways, Jingle is quite capable. He is able to work his way into a variety of elite circles, fooling everyone with ease. The name he takes on — “Charles Fitz-Marshall”— is enough to ingratiate him to the likes of the Hunter family, who care far more about appearances than they do substance. Although the Pickwickians sometimes fall into this same trap, Pickwick has a strong moral sensibility, which he feels Jingle has violated. As such, he summons Sam to try chase after Jingle and make things right.
