How did Tita find Nacha at the end of Chapter 2?

When Nacha tastes the icing to see if Tita’s tears changed the taste of it she becomes filled with a feeling of longing and spends the rest of the night crying. Nacha remembers all the wedding preparations she had made in 85 years of life without ever being the bride herself. Though she once had a fiancé, Elena’s mother would not allow Nacha to marry him and she spent the rest of her life single. In the morning Nacha is so weak from crying that she cannot help with the wedding.
