To facilitate the marriage of Welborn and Lady Allworth, Sir Giles advances Welborn a thousand pounds. He also discusses his plans with Lovell, revealing more of his intentions and his dark character, so that Lovell breaks into a "cold sweat" listening to him. (With each of his appearances in the play, Over-reach's expressions of his villainy become more flagrant and overwrought, leading up to the denouement of the final scene.) Marall sees Welborn's apparent ascension in fortune, and, chafing at Over-reach's insulting and brutal treatment of him, decides to switch allegiances; his command of Over-reach's legal papers gives Marall a key advantage in seeking his own revenge.
