At the end of every episode, the card for the production company Spitzer Holding Company features a variety of items they specialize in. In this episode they list Water Slides, Fax Machines and Home Delivery Available.
Amy's fake name tag says "Lucia". America Ferrera would later name her daughter, born in 2020, Lucia.
Dina's apartment is seen for the first time. In Brett Is Dead (2017), Garrett had said that he'd had sex with Dina in 3 different houses and he wasn't totally sure any of them were hers. This would seem to verify that the apartment is in fact Dina's, given the bird paraphernalia, personal effects and awards, and shrine to her bird Jeremy, who died in 2016.
Some of Dina's birds' names are Sebastian, Cockatrice, Birdie, Portobello, Squeedledee, and Russell Crow.
In Dina's apartment, two sashes can be seen in the background. They read "Hall Monitor" and "Recess Monitor".
