Amy most definitely served as a foil to Jimmy, most specifically in her relationship with her parents compared to Jimmy’s. While Amy’s mother had already passed away, it felt as if she shares a stronger connection with her and than Jimmy shares with his own mother who is still alive. The fact that we are talking about Amy’s adoptive mother underscores the fact that quite often family isn’t about blood. When they hear the news that their father has died, Amy is stricken with grief and shows us an example of how most would react in that situation. That is juxtaposed with Jimmy’s complete non-reaction, not that he isn’t entitled to it.

In the powerful moment when Amy rejects Jimmy, it once again reinforces how little blood relations means to Amy. She doesn’t know him and has only met him through a tragedy. And there is no point in trying to establish a relationship with him because to Amy–Jimmy is a stranger who she now associates with grief. Just as Amy has no desire to meet her birth mother, she would probably rather forget about Jimmy’s existence.
