From a purely technical standpoint, this comic was very easy to make. From an emotional standpoint, it fought me every step of the way.
Susan was first introduced into EGS
with the intent of her being something of a stuck up secondary character. The half-lidded look of her eyes was meant to reflect this. She quickly took on a life on her own as I tried to figure out her motivations and back story, and it didn't take long for her to become a main character.
I have frequently seen Susan described as having a "bored" look on her face. For a long time now, I have seen it as something else.
