Greg responds...

I can't believe I haven't answered this before here. But since Todd didn't field this one, I guess I haven't... or at least not here at ASK GREG.

Anyway... No.

We always knew there was something special about Owen, but didn't know what it was at first. Then when we first started working on "The Mirror" and created Puck, it suddenly occured to me that Puck was Owen. An epiphany. I immediately called Brynne Chandler Reaves and Lydia Marano. The conversation went something like this...

Greg: "I just realized: Owen is Puck!"

Brynne & Lydia: "We know!"

It was just so right. The references in "The Mirror" to Puck "serving the human" and in "City of Stone, Part One" to Owen being "the tricky one" were put in post-epiphany.
