The girl’s behavior is wildly confusing, to say nothing of intimidating: Roy is described as a pretty small kid, while this girl is, like Dana, big and strong. When Roy notes that he doesn’t really want boys to see the girl intimidate him, it shows he does care about making friends in Florida—or, at least, he cares about impressing other boys and looking reasonably strong and confident. As with Miss Hennepin and Dana, this girl also seems to know something about the running boy that she doesn’t want to share with Roy.
