] I was also hoping for a non-magic explanation (snip)

So was I. I was thinking at the end it would turn out that Parrish was drugging Caroline since she always seemed dazed. I didn't care for the hocus pocus.

I began to suspect Parrish around the time that he showed up with scratches on his face. I thought that his explanation about being scratched by Caroline's ring was a cover up and that, in fact, he sustained the scratches while murdering Kendall. So right person, wrong clues.
