This is a sweet moment between Ollie and Makani, and one that advances their relationship. Ollie has seen how Makani feels alienated and homesick in Osborne, so he's taken her to this “ocean” of corn to remind her of the beloved hometown she left behind. This is another example of how Makani’s relationship to cornfields changes according to her mood and the people she’s with. Normally the corn is stifling and a reminder of her exile, but with Ollie, the cornfields take on a romantic, beautiful connotation. Again, place doesn’t make a person happy or miserable: their attitude and relationships to others are what determines their satisfaction with life.
