The Eleven O'Clock Number: Specifically discussed; Rebecca explains the origin of the term and its usage in musicals. It's even called "Eleven O'Clock" and happens at 11 am.
Rebecca goes from her kitchen to a dark space with a single spotlight.
Rebecca: Oh, good, an abstract theatrical space. Now I can actually think.
During the reprise of "We'll Never Have Problems Again" she exclaims "I know I have to move to the next song but I wanna keep disco-ing!"
Reprise Medley: Reprises not just the theme songs from each series but also "West Covina", "A Diagnosis", "The Darkness", "We'll Never Have Problems Again", "I'm A Good Person," "The End of the Movie" and "You Stupid Bitch".
"West Covina (Final Reprise)" (sung by: Donna Lynne Champlin and Rachel Bloom)
Nathaniel quits being a lawyer and gets a job at the zoo, a reference to his love of going to the zoo in "Josh is a Liar". He also says, in Spanish, about the monkey he is holding that "His eyes look like my eyes," which is a lyric from "I Go to the Zoo".
Rebecca says she only revealed her musical flights of fancy to the imaginary Dr. Phil and the Dream Ghost, references to "I'm So Happy That Josh is Happy!" and "Josh Has No Idea Where I Am!".
Crusading Lawyer: Paula threatens to quit her job if the firm won't let her do pro bono cases for people who need representation.
Earn Your Happy Ending: After four seasons of mental illness, delusions, heartbreak, a suicide attempt and a spell in jail, Rebecca at last realises that her happiness isn't dependent on someone loving her, but on her doing the thing that she loves to do above everything else: make up songs. The final line of the show is "This is a song I wrote."
Exact Words/Fun with Subtitles: The cut from the open mic night to Rebecca on the toilet angsting about her decision is simply titled "earlier." It is intended to imply that the flashback happened earlier in the day, rather than a whole year earlier.
Expository Hairstyle Change: The first explicit indication that the open mic night happened a year later than we think? George's hair is in a ponytail, which he said earlier would take a year to grow.
Grand Finale: The last episode, with the characters' journeys coming to a close and Rebecca deciding to choose herself instead of a romantic relationship (for the moment).
Imagine Spot: Turns out all of the songs were Rebecca's. Paula realizes that she's got a talent for songwriting if she's been making relevant songs of many genres in her head for so long, and encourages her to pursue that.
In Love with Love: Josh isn't so much in love with Rebecca as he is ready for a committed romantic relationship. Rebecca realizes this and lets him go, and by the epilogue he's the only one of the three who's in a relationship with someone else.
Leaning on the Fourth Wall: At her open mic, Rebecca says that it wasn't about her "ending up" with anyone, as it was her growing to the point where she could have a romantic relationship.
Leitmotif: When Rebecca speaks about the Character Development of each character, a piano version of their respective signature songs are heard underneath:
"Women Gotta Stick Together" for Valencia
"The Moment is Me" for Heather
"Face Your Fears" for Paula
"What'll It Be?" for Greg
Maybe Ever After: Ultimately Rebecca doesn't end up with any of the three, and the epilogue is less about her choosing as it is her saying that she's finally ready for romantic love. Of the three, Josh is explicitly in a serious relationship, and Greg is explicitly single.
Medium Awareness: When Paula confronts Rebecca about her habit of spacing out:
Rebecca: When I stare off into space I'm imagining myself in a musical number. That's how I sometimes see big moments in my life, as musical numbers. And because I do that, so does the show. And by show, I mean the very popular BPD workbook acronym, "Simply Having Omniscient Wishes".
Sitcom Arch-Nemesis: Rebecca and White Josh remain this even in the touching finale. He tells her to her face that he's the only one who's never taken to her and never will, and she is so unconcerned with his suffering that she's completely forgotten him losing his home and all his possessions in the last year. note She does remember that something happened to him, but she just vaguely recalls that it had something to do with the circus. Because she was at the circus when she first heard about it.
Take a Third Option: Rather than choose one of the three, Rebecca takes an entire year off to continue growing.
Time Skip: The epilogue takes place a year after the three dates.
"Where Are They Now?" Epilogue: The ending. Rebecca has turned to songwriting as her passion, Paula opened up a pro bono arm of her firm to continue helping other women in jail, Nathaniel quit the firm and now works as the zoo's lawyer, Josh found his own true love, Greg is running his father's Italian restaurant, Valencia and Beth got engaged, Darryl and April have a full blended family with a fourth on the way, Hector and Heather got a new hot tub, and Whijo's apartment burned down with him losing everything on the same day his childhood home burned down.
