KING HENRY.
[Aside.] I know not what to say; my title's weak.--
Tell me, may not a king adopt an heir?

YORK.
What then?

KING HENRY.
An if he may, then am I lawful king;
For Richard, in the view of many lords,
Resign'd the crown to Henry the Fourth,
Whose heir my father was, and I am his.

YORK.
He rose against him, being his sovereign,
And made him to resign his crown perforce.

WARWICK.
Suppose, my lords, he did it unconstrain'd,
Think you 't were prejudicial to his crown?

EXETER.
No; for he could not so resign his crown
But that the next heir should succeed and reign.

KING HENRY.
Art thou against us, Duke of Exeter?

EXETER.
