How does Laker's life change after his mother meets Rick?

Prior to Audrey's marriage to Rick, Laker is the man of the house, and he tries to take care of his mother, including lying to her employers when she is too depressed to get out of bed to go to work. In return, Audrey gives Laker love. However, when Rick comes along, Audrey sees that she can be dependent on him instead. Explaining to Laker why she is marrying Rick, Audrey says, "Laker, he works hard and he wants to take care of us." When Laker responds, "I can get another job. A real job. I can take care of both of us," Audrey cruelly answers, "Laker, you're just a kid."
