These are my predictions for clan of the cave mom:
Marge and Luan will get into a fight during a debate at Springfield elementary.
Their argument will disrupt the meeting and start a fight among the school staff.
Marge and Luan will smear each other through posters and social media.
Their feud will interfere with their sons' friendships.
They will keep Bart and Mill house from seeing each other.
Kent Brockman will interview both of them separately about their feud on the news.
Lisa will try to sabotage Marge's campaign to prevent her fight with Luan from going any further
Marge will drag Homer into her fight and force him to help.
Luan will humiliate Marge to big that it'll ruin her image.
Bart will sabotage Luan so Marge and win and he and Mill house can be friends again.
Homer will talk to Marge and make her realize she's taking this feud too far.
Marge and Luan will make up and realize they aren't so different after all.
The school will settle their feud by using both their ideas and eliminating the other participants.
There will be a scene before the credits of Marge and Luan gossiping and talking smack about the other women they know.
