The Second part of King Henry the Sixth — Act 2, Scene 2: London. YORK'S garden.

In York’s garden, York meets privately with Salisbury and Warwick and asks for their opinion of his claim to the English crown. He lays out his genealogy in detail, tracing descent from Edward III and arguing that the Lancastrian kings took the throne unlawfully from Richard II. Salisbury and Warwick accept his reasoning and kneel to him as their rightful sovereign. York, however, says he is not yet king and must wait until the house of Lancaster is overthrown. He also tells them to keep quiet and watch the enemies around King Henry, especially Suffolk, Winchester, Somerset, and Buckingham, while they wait for the right moment.
