At 2:58 Fiona says "I should have made her go on the pill" to Sean, talking about Debbie's pregnancy. But Debbie was on the pill before the pregnancy happened. Fiona took her to Planned Parenthood years ago to get the pill.
When Debbie is on the L with her flour bag, the sign on the side of the train that tells which direction the train is traveling sometimes shows that it's a Blue Line train headed toward O'Hare Airport (even though she gets on at Green/Orange stop) and sometimes shows "Not in Service".
At 26:00, Debbie receives a text from Fiona. Fiona's text is in green on the right side, which would make it Debbie's text, not hers. Hers would be in gray and on the left side of the screen.
