Who now fetches the water in the Lapham household? How does Johnny find out and how does he feel about it? What plan do Johnny and Cilla make? From chapters 5-6

Now that Johnny is gone, Mr. Tweedie makes Cilla fetch water for the silversmith. Johnny is upset to see the pretty, delicate girl being forced to do hard labor. He carries the water for her and introduces Cilla to Goblin. He asks Cilla to meet him on Thursdays and Sundays––or whenever she is sent for water––so that he can carry it for her.
