doris says,''you'll see'' to her father.what does she mean?

Dear student 

Doris says these words to George. George does not understand why Doris was crying because he didn't witness his mother (Mrs. Fitzgerald in reality) behaving in a rude manner towards her. He wonders out loud, saying that there can't be anything to cry about. Doris replies by saying that he'll understand once he talks to Mrs. Pearson, and witnesses her rudeness personally.
