Hello. You did not provide the excerpt to which this question refers. Which makes it impossible for it to be answered accurately. However, I will try to help you in the best possible way.
To be able to understand Cal's point of view about himself, you have to read the text and recognize the tone that the text emits. The tone is the feeling that the text gives to the reader. If that tone conveys a positive feeling, it means that Cal's view of him is also positive. If the tone expresses a negative feeling, it means that the lime view on itself is reactive.
