Ned proposes, but Helen dares not accept. There is a big ball that night. Grace tells Helen, when she meets her on her way to the ballroom, that she is going straight to Ned. Ned proposes again to Helen, but just then a page comes rushing in and cries FIRE. It is the servants' annex, Helen finds Grace in a heap on the floor of her room and rescues her, but is badly burned herself. Grace takes Helen home with her.
