Read the following paragraph and extract the answer for the question: What is the name of the character who scolds Hector for fighting?  Hector Villa is a young Mexican national and border-crossing migrant and worker with boxing abilities mirroring his late father's. He could perhaps be good if he learned to think along with his pummeling. Despite all of this, Hector is a hard worker on a Texas farm who does what he can to provide for his ailing mother which includes pulling in a few side dollars from small-time, illegal gambling fights. Tito, a "coyote" (a person who helps smuggle people across the border) spends his days as a snake catcher but at night, helps smuggle immigrants across the border. After winning a fight in a local mechanic's garage, Hector tries to get another fight but the entertainment is interrupted by Tito who scolds both Hector and the owner due to the fact that Tito could  get into more trouble for illegal gambling fights as if smuggling illegals across the border isn't enough. Corralled, Hector goes to change but is followed in by another illegal; Maria. It soon becomes known that they grew up together as kids and it also becomes apparent that Hector dislikes her (mostly because of her sarcastic teasing). Tito hands Hector medicine for his mother and the three head back to the farm where they all work. After settling all of the immigrants in, Maria goes into her own suite with Hector and makes herself at home despite Hector being less than welcoming. Hector then goes to his mother Rosa to give her the medicine but it becomes apparent that she is getting worse. Hector begs her to not go out to the fields the next day but she declines stating "No work, no pay". She scolds Hector for fighting to make money and reminds him that a fighter's lifestyle gave his father nothing. Maria walks in and gets reacquainted with Hector's mother who comments on how much she has grown  and how beautiful she has gotten after nine years apart.
A:
Rosa
