Fan Casting Zatanna in Constantine

In the scene after the credits of the last episode, the magic can be seen paying a visit to John's mansion after some time apart, where they begin to talk about a certain subject raised by her. - Zatanna, we've already talked about this, I don't think it will work, like the last time. - Is it what you think, or is it what you want? – Questions Zatanna laughing – Zatanna… we are not good for that. Why do you even have this in mind? Before the screen goes dark, Zatanna turns her top hat with a smile, before giving Constantine the answer: - Answer me something, John. If they can have their own 'Justice League'... why can't we?
