Aria Knife Murder-Nights Sketch

To the second image in line of the video. Its Aria wielding a knife, full of emotions. She's sad, angry, full of adrenaline, and excited. 

The central sun of the dual tailed spiral galaxy, like our galaxy, is the core.
Its like the hidden central force behind the ancient "good and evil" symbol. 
The "good and evil" symbol looks like two tear drops spiraling.
Aria adopts a symbol for the spiral galaxy, as originally found on her sweater...later on, to symbolically transcend the idea of good and evil as she pursues justice. 
What can you expect, her friends were killed and she wants vengeance because her entire life up to that point is shattered. She's a clever girl.
