Anger Born of Worry: Speckle explodes with anger at Bertie when she comes home, but only because he was worried sick when she suddenly left and didn't call him back for several days.
Cerebus Retcon: Inverted. Bertie seemingly jerking off privately in the bakery's bathroom? Baker Barb was also in there, standing right behind her the whole time.
Continuity Cavalcade: Multiple characters that have appeared across the season appear during the sequence of Pastry Pete's video going viral and the neighborhood helping with cooking for Sweet Beak.
Embarrassing Slide: When Bertie is giving Tuca her presentation on her new bakery, one of the slides details on "Why Bertie SHOULD be allowed to have a boy-girl slumber party".
Bertie: Oops, how did a slide from high school get in there?
Engineered Public Confession: Tuca is sneaky enough to take a video of Pastry Pete threatening Bertie when she confronts him about stonewalling her. After Bertie puts it up on social media, Pete's business is destroyed.
Eye Scream: When Tuca tries to call Terry, her dialing finger flies all over the place before poking her in her eye.
"Birdtown needs another bakery like I need a giant hawk to shit in my mouth."
Voice Clip Song: Pastry Pete's "I made you, and I can ruin you" ends up getting turned into a remix during the montage where the news is spreading online. A phone is even shown dancing along to it during a scene transition.
You Mean "Xmas": "Molting Season" and "Molting Day" is an overt stand-in for Christmas. At first it seems non-denominational as well, until Tuca complains about how pervasive it is, to which a festively-dressed retail employee responds "You're telling me, I'm Jewish."
