Jane is giving Ziggy a bath, and he keeps talking about a family tree project.
Good thing the project isn't due for a week. Jane has plenty of time to get back to her book, which has some racy scenes in it.
The racy scenes make Jane flash back to an unpleasant encounter she had. It's hinted at that this unpleasant encounter was the moment of Ziggy's conception.
Ziggy keeps talking about this family tree project. He says it's due tomorrow.
But it isn't…or is it?
Jane goes to check. Oops. The family tree is definitely, definitely due tomorrow.
She texts Madeline, asking if Madeline has any cardboard. It's too late to go and buy any; all the shops are closed.
Then, everything unravels. Ziggy doesn't want to get out of his bath and starts screaming.
Jane screams back.
Ziggy screams louder.
Jane screams back, also louder. She's panicking and feels like a terrible mother.
In the midst of all of this ruckus arrives Madeline, with a fresh sheet of cardboard.
