- Always Someone Better: The Abbott squad are astounded to see that Addington Elementary, the charter school down the street, is in much better condition compared to their school.

- Failed a Spot Check:
- Apparently Ms. Howard has confused multiple white celebrities with black ones who share a similar name. Rather then correct her every time, Janine and the others decide to play along for her sake.
- Devon, the cafeteria man, initially believed that Ava was giving away the grant money and came up with a dream presentation that wouldn't benefit the school.
