The one that told me about the Arrow easter egg in Constantine would be here: https://www.facebook.com/dctvuniverse

The one with that user name gave me the info. How he aquired it, I hadn't asked.

As for Zatanna, I learn that in a video I watch in youtube from back in mid august. Some was confirmed source information, the rest was speculation based on that. At any rate, that youtuber is certainly my favorite speculator and recapper for the Arrow-verse. Here is the link http://www.youtube.com/watch?v=U7LtMY6ilf0&list=PLOIeYdZ3QczwCLH9RIm-7ui56ameRYmdQ&index=17

Hope this helps!
