I think that Tess wants Aron to be exactly like her. She said “I hope Aron knows how to play Monopoly”. She also said that “I hope Aron would like being on an island like I do”. Tess likes  playing monopoly so she wants Aron to be like her. She also told Libby  “don’t you want Aron to be like you?”  Tess also keeps asking Aron questions like do you no how to play monopoly or do you like boats? This shows that Tess is trying to get to know Aron but is also trying to see if they have the same interests.  At this point Aron and Tess don’t really have the same interests other than boats and Tess dose not like it. That is why she keeps asking random questions to find the same interest.
