What happens in Act I Scene 5-6 in the Miracle Worker?

Arthur, realizes that Kate will never find the key, so he takes the ladder and climbs up to Annie’s room, telling her that he’ll have to carry her down. Annie tries her best trto look “as composed and ladylike as possible.” James retorts “might as well leave the l, a, d, d, e, r,” an implication of her needing it again. Annie realizes that she has failed her first test with Helen.

Annie notices Helen sitting by the pump, oblivious to the chaos around her. The lights dim, and Annie walks over to observe her young pupil, a little awed. When Helen is satisfied that she’s alone, she opens her mouth, revealing the key. Annie can’t help but smile: “You devil,” she says, “You think I’m so easily gotten rid of? You have a thing or two to learn, first. I have nothing else to do.”
