Damn, for a sec, I thought Hizumi was going to school her mama but seems we now know who taught her Talk-no-Jutsu...
Calling it out tho : Hizumi Dad left because even after trying to become better, he realized that his wife would never respect or support him like he did for her.
On a side note, I have mixed feeling about the Theory that Shinba Mom would be now dating Hizumi Dad : on one side, it feels a bit far-fetched and too coincidental just for the purpose of drama but on the other, the idea of Hizumi Mom discovering that 2 members of the Shinba Family took a loved one from her and made them happier than they were with her is my kind of Schadenfreude, especially after that chapter... !!
