From previous spoiler, we've learned that Katherine's medicines are working and Susan's son is in slow math group at school.
Now, a source tells us that Katherine doesn't like seeing the person that she's become. Hmm, is this a wake-up call for her?!? Also, it's not just Susan who's concerned about the possibility that his son's in the slow math group. Gaby's daughter, Juanita, might be in the same situation. So both will be in desperate lengths in order to find out more about their kids' school performance!
