Ollie’s bright, lively room clashes with the rest of his house, which memories of his dead parents makes gloomy and uninviting. It’s also a huge contrast to Makani’s room, which is gloomy and devoid of personality. The lively quality of Ollie’s room reflects, perhaps, his mental balance. Unlike Makani, who remains tied to her past and is mentally unwell because of it, Ollie seems to have made peace—as much as anybody can—with his parents’ deaths, and he's managed to make a life for himself in the aftermath of unspeakable tragedy.
