Where Wolf?

In the last few chapters of New Moon by Stephanie Meyer, the chief character, Bella Swan, finds that her best friends Jacob is acting very strangly. He's acting evasive and harsh not to mention the complete physical transformation he's completed. Jacob cut his long black hair short, his skin turned a rustic brown, and his face became oddly familiar with the expression of seriousness. Bella felt confused, hurt, and worried about Jacob becuase it seems to her that all these changes have only occured to Jacob since he has been hanging out with a new, and shady, group of friends. Bella can only guess to what prompted these sudden changes, but at first she suspects that hes entered some kind of cult. But it turns out that she is extremely off. These chapters just go to show that you can't jump to conclusions in confusing situations. There could always be another reason.
