After he confers with Scout about her verbal exchanges with Francis, Uncle Jack understands why she has acted as she has towards her cousin.

Subsequent to Scout's punch to the mouth of Francis, Atticus loads her into their car and they return home from Finch's Landing where they have spent Christmas. But, because Scout has been so angered that Jack does not let her explain why she has struck Francis in the mouth, she has told her uncle that she will never speak to him again for having been so unfair. Troubled by Scout's words, Jack decides to drive to the Finches' and clear up any misunderstanding. When he knocks on the door, Scout angrily tells him, "Go away!" But he insists on resolving their conflict. So, when he allows Scout to explain that Francis has called her father a "n*****r-lover and repeated part of what he has overheard--

"Atticus'd be the ruination of the family an' he let Jem an me run wild...." (Ch. 9)--

Now Uncle Jack becomes disturbed not by Scout, but by the words of Francis. He then promises Scout,

"We'll see about this....I've a good mind to go out there tonight.....The idea of--wait'll I get my hands on that boy...." (Ch.9)

Despite her satisfaction that Uncle Jack now understands, Scout begs him to not tell Atticus about her fight with Francis, explaining that she would prefer that her father believe that their fight was about something else, rather than the upcoming trial. He agrees and good relations are resumed as her physician uncle tends to Scout's skinned knuckles.
