Without a specific text or play reference, it's not possible to determine exactly which two family members agree to let Annie take over. Such a decision in literature generally signifies a turning point in the plot and character development.
Step-by-step explanation:
The characters in question, who finally agree that the right thing is to allow Annie to take over, are not explicitly named in the information provided. However, based on similar thematic discussions in various plays and literature, such agreements typically involve key family members reaching a consensus to support someone taking a significant new role or responsibility.
