What are examples of irony in Romeo and Juliet Act 5?

5.1: Situational irony: Romeo believes Juliet is dead and drinks the poison, even though she is still alive. Juliet then wakes up to find Romeo dead, and stabs herself with his dagger.

5.3: Verbal irony: The Prince says that the Capulets and Montagues must stop their feud, or else they will be punished. This is ironic because the feud is ultimately the cause of Romeo and Juliet's deaths.
