The setting is Gloucester's castle. Oswald reveals to Regan that Albany's forces have been deployed, but with much reluctance. Regan is more interested in the letter that Oswald carries from Goneril to Edmund. Regan insists that the letter be given to her, because she is aware of Goneril's amorous glances toward Edmund. Regan tells Oswald that Edmund is to be reserved for her, since she is now a widow. Regan also directs Oswald to kill Gloucester if he finds him.
