The Premise: Oh come on, now. You know the idea here, right?
(note: instead of dialogue in the speech balloons, I will instead describe the objects to put in there in place of actual speech, contained within . e.g [UPSIDE DOWN TOILET]. Figure it'd be the best approach to doing her magic without saying anything, and it should add a nice touch to it all.)
Zatanna is chasing an imp down a new york alleyway towards a dead end.
The imp's back is pressed against the wall of the dead end, panicked. Zatanna is striding over, one hand on her hip.
Close on Zatanna as she points to the ground, mouth all agape and surly as if saying something really unpleasant to the imp.
Zatanna: [MIRRORED EXIT SIGN] [DOWNWARD ARROW] [FIREY PIT]
The imp flails in pain and grows in size as it's pulled by an unknown force through a dark portal on the ground.
The imp has grown into a large fire demon, a fair foot or two taller than Zatanna and is pulling itself out of the hole, lunging towards Zatanna, who is jumping as if surprised.
Close on Zatanna as the imp/fire demon's shadow falls over her, backlit by his bright orange flames. One of her hands is up on her mouth in shock.
