Kate and Anna’s bond that they have with each other is much stronger than most normal siblings because of Anna’s role as a donor for Kate. The reason why Anna was born was to help keep Kate alive. “See, unlike the rest of the free world, I didn’t get here by accident. And if your parents have you for a reason then that reason better exist. Because once it’s gone, so are you.” That reason was to be Kate’s donor. That means that Anna was born to form that bond with Kate because they can’t live without each other. Anna, for better and worse, feels so strongly connected to Kate that she compares their relationship to that of Siamese twins at one point. Kate, though she behaves as any big sister would, also shows immense gratitude to Anna for going through what she goes through for her
