Like Father, Like Daughter -- A DSMP OC Story

Now, we all know Wilbur isn't the best father.
He's neglectful, impatient, a bit narcissistic. How Sally fell for him in the first place is a mystery to us all. And for the 10 years they were together (married for 7), they had two lovely children. Fundy and Anna. Fundy was a fox hybrid that looked nothing like either parent while Anna was practically a carbon copy of her father.
Wilbur had a sneaking suspicion that Fundy wasn't his true son although Sally always claimed that he was. Fundy and Anna were twins for goodness sake!
One night, while arguing with Sally over the true parentage of his son, he attacked his wife in a fit of rage. Anna saw her mother bleeding out and screamed for her father to stop. He dropped the broken bottle, falling to his knees. The poor girl yelled at her father to help her mother. He lifted the dying woman up and carried her to their shared bedroom. Anna sobbed and told her father to save her. He refused. Instead he called upon his own father for help. Told them his wife had a deadly disease. That's the story he told his children. That story was false and Anna knew it.
The young girl could care less about her father. She knew he was a rotten liar. He didn't deserve her sympathy or her kindness.
12 years put distance between the two.
What happens when she goes back to him?
