Final answer:
Samantha admits to lying about Stephen being her brother, has never seen him before, and has an undisclosed illness related to lettuce poisoning. Information about Stephen's family and his character is provided through interactions with other characters, which gives depth to Samantha's social surroundings and relationships.
Step-by-step explanation:
Within the various texts provided, Samantha makes clear statements regarding her relationships and those of her acquaintances. Specifically, Samantha admits that Stephen is not her brother and she had never seen him before, which reveals that her relationship with him is not as it had been presented. Another character, Rosa, mentions Stephen working hard and having siblings employed at different places, however, this information does not relate directly to Samantha. Additionally, in a separate instance, Samantha's illness due to lettuce poisoning is mentioned, and through a character named Jasmine, we learn that Samantha behaves differently when she is unwell compared to when she is in good health. Lastly, there is a poignant scene where Stephen's dignity in the face of verbal abuse is made evident, and the abuse includes an insulting reference to Stephen's sister. Taken together, these excerpts paint a picture of misunderstandings, deceit, social standings, and personal relationships.
