Who is Hilda? How does María Teresa feel about her? Why does she feel this way?

Hilda is a revolutionary and one of Minerva's new friends, of whom Maria Teresa disapproves. Sor Asuncion says that Hilda has a bad attitude, and Maria Teresa thinks she is an orphan. In June, guards come looking for Hilda, who is hiding at Inmaculada Concepcion, pretending to be a student.
