I would call his saying he felt drawn to Beacon Hills when we know the Nemeton is drawing supernatural things to Beacon Hills a pretty solid hint (at least), but whatever.

Also, in this most recnt episode, he seemed pretty well aware that Derek wasn't entirely human and didn't seem at all surprised by that fact. Again, a hint.
