King Lear Act 4, Scene 5

Regan and her sister begin to quibble over Edmund, the heir to the throne. Regan tries to convince Oswald that she is better suited to marry him, since she is a widow. Regan tells Oswald to share this with Edmund. Also, she tells Oswald that she would give him a reward for killing off Gloucester the traitor. Oswald accepts this offer, and goes on his way.
