Archie was obliged to allow Rose to continue to stay at Misselthwaite only in that she was Lilias's sister, and he did not wish to further cause any sort of greater rift in their sisterly relationship though Rose had always been unkind and cruel in her behaviour towards Archie. One such example can be given at the event of a society ball.
It was the third occasion Archie and Lilias saw each other. Rose and Albert were present along with Lilias's and Rose's parents. Archie catching sight of them approached and began a sweet introductory coversation with Lilias while her parents listened on. Moments later, Rose swiftly used the pointed front toe of her shoe to suddenly propel Archie's walking stick/cane out from the supported weight of his body causing him to fall harshly to Lilias's feet. Ill-prepared to catch himself, he violently landed body first-not hands or arms-flat upon the floor. Rose was so quick about it, no one but Archie knew it was her foot that caused him to tumble. Archie, thinking better of her at the time, thought it was an accident.
"Are you all right, Sir? Lord Craven?" Lilias did not hesitate for one moment before bending to his aid. "Here. Let me help you. She raised him up again and tenderly dusted off the arm of his tailcoat and placed her hand over his in concern. Lilias's parents immediately recognized such an intimacy and chided her for it later that night. Archie knew her parents were shocked, so he gently withdrew his hand from hers, though he had no desire to.
"Perfectly, Miss. I sincerely apologise." He paused. Lilias's father handed him his walking stick.
"Forgive me, I... must take my leave." He spoke gently as his heart beat quickly but his outward appearance remained calm. He was embarrassed and ashamed.
"Lord Craven, you mustn't go." Lilias followed him.
He had a melancholy look upon his face when he turned in profile to look at Lilias.
"May I...I would like very much if...would you care to... dance with me?" She sweetly spoke looking for the proper words.
Archie had a surprised look with an underlying or hidden expression of delight.
"That is, if you're not hurt. Are you certain you're all right?" Lilias continued.
Lilias's sweetness and beauty was more than Archie could resist.
Archie gave her his arm as a silent response.
They spent that night spinning and twirling to waltzes on the dance floor.
