"Daughter" is a minor character in Season 2b of Fear.
After leaving the house he has shared with Sofia and Juan, Nick wanders for most of the day before settling down for the night in an apparently abandoned house. However, while he sleeps, this girl and her mother come across him. His bloody appearance scares the mother, and she hysterically screams at Nick while hitting him with a baseball bat while keeping her daughter behind her. The mother doesn't seem to understand English, as she does not allow Nick to retrieve his supplies. She continues to scream at Nick after he leaves the house.
It is unknown what happens to this girl or her mother after this.
