I didn't know if you guys knew about this, but he was really good. Spencer(J.J. in TDZ) played this little boy who I think was supposed to be an animal reaper. I thought it was him but I wasn't sure. It's in the season one finale "Rest In Peace"

I recently viewed the DVD myself, and was at a friend's house when I did so....unfortunately I had to leave just after I pointed at Spencer and told my friend "Hey, there's J.J.!". She, too is a DZ fan, and she'd already seen the ep. and told me about his part.
