Here's a little explanation to make things easier...
In the first three panels there's a glimpse of Scarlet's childhood. She was in agricultural slavery sold into i by her mom. She had short hair back then because she wasn't allowed to have it long. She's being beaten by a girl there that's also a slave, of which is very abused as well.
And as an adult, she's thinking of that event which she can't get over. This is about four years in the past of modern day. This is where she started to abuse Felix.
That's all I could say, she did worse then what she got, so there's probably something wrong in her head.
