describe the end of the act 1

Here is the Gradesaver summary. Feel free to use the study guide for the rest of the play (link below): "Keller enters and says that George, Ann's brother, is on the phone. Ann exits to answer the phone. Keller expresses puzzlement that George is calling from Columbus, where his father's prison is. Keller is suspicious that George and Ann are trying to open up the case again, and Chris is angered by the insinuation. Keller changes the subject and says he wants to rename the business for Chris, but Chris is uneasy with the proposition. Keller suspects that Chris is ashamed of their money, and he insists that it is good money, moral money. Ann returns and says that George will be coming that night. She and Chris leave. Mother enters and is shaken by the fact that George needs to speak to Ann. She asks what it is Steve has to tell George that has required George to take an airplane from New York to see him. Keller insists there is nothing, and Mother twice questions his resolve on that matter. Mother finishes with a warning that Keller ought to be smart."
