Crazy Ex-Girlfriend is a dark comedy series, so there are moments that are pretty dark...
- The song "Feelin' Kinda Naughty" has Rebecca wanting to lock Valencia in the basement, taking over her identity, cutting off her hair, killing her and wearing her skin as a dress. Sounds like something that should be on Supernatural or Criminal Minds.
- Rebecca threatening to gut a woman's husband like a fish if they didn't tell her that she's a good person in "I'm a Good Person".
- Moments later, she forces everyone to dance at knifepoint.
- In the season 2 premiere, after Josh asks Rebecca what she meant when she said "I moved here for you", Rebecca starts realistically gaslighting him into believing it was all in his head.
- The Santa Ana Winds in "Josh is the Man of My Dreams, Right?" are surprisingly creepy. Between the music, Paula's nightmare, Eric Michael Roy's manic performance and the general sense of weirdness, it does kind of feel like reality has gone askew.
- In the Season 2 Finale Josh has jilted Rebecca at the altar, and Rebecca, not having an idea what's happening, she almost walks off a cliff.
- Nathaniel helping Rebecca get revenge on Josh, by targeting his family, getting his sister kicked out of school, his father a fugitive and MURDERING his grandfather by taking away his oxygen tank. Thankfully Rebecca doesn't go through it. But what if Rebecca didn't ask Nathaniel what he did and all these things happened...
- Rebecca's song confessing to Josh ALL the things she did ever since she moved to West Covina. Take it from Josh's POV, he realizes that this woman has been stalking him, and watched him have sex on two different occasions, and he almost married her. Well, at least he's free of his guilt.
- The end of the episode, Rebecca just realized she has told Josh EVERYTHING.
- 3x03, Josh is about to lose his friends after all the lies Rebecca said on the feminist website. So he retrieves the file about Rebecca that Trent gave him in the Season 2 finale. Which was about Rebecca trying to burn down someone's house, and was sent to a mental health institute, and Josh almost married her...
- Take this from Rebecca's POV towards the end, she realizes that everybody knows about her past life, and has no choice but to flee town.
- It seems that Josh seems to be getting away with everything, from abandoning Rebecca, losing his guilt afterward and after everyone has turned on him because of lies, the heads now turn to Rebecca after the truth is revealed.
- The promo for "Josh's Ex-Girlfriend Is Crazy"
. - "I Never Want To See Josh Again" is full of this. First Naomi discovers that instead of revamping her resume, Rebecca has been researching ways to commit suicide. Then Rebecca, after thinking her mother has changed into the loving mother she always hoped for, discovers that the strawberry milkshakes she has been drinking were spiked with anti-anxiety medication. She then finds out her mother was going to have her committed once Rebecca had settled down more (though in fairness to Naomi, she was absolutely right that Rebecca was in danger of hurting herself). Rebecca then runs away from home and gets a flight back to Los Angeles. During the flight, she attempts suicide by overdosing on the medication. She stops herself at the last minute and tells a flight attendant that she overdosed and needs help, but seeing Rebecca at her lowest point is utterly terrifying.
- In "Josh is Irrelevant" Rebecca is diagnosed with Borderline Personality Disorder. Against her doctor's recommendation, she searches for what that means and finds horrible headlines saying that BPD patients are considered difficult to cure; denied appointments by psychiatrists because of said difficulty, the patients' unpredictability, and impulsiveness; and that 10% commit suicide. The worst part is that all of these are Truth in Television.
- In 'Oh Nathaniel, It's On!' Rebecca becomes jealous of Nathaniel's new girlfriend Mona. She turns to the dark side of the Internet to find information about her, just like she did with Anna in Season 2. Rebecca overindulges in doing this and even hires someone to take her out. Just to mention, Rebecca is on hormones.
- Trent returns and is even creepier than ever. It is revealed that he knows about Rebecca ordering a hit on Mona, and was keeping tabs on her IP address, and blackmails her about it.
- Later on, Rebecca and Paula discover that Trent has been stalking Rebecca, EVER SINCE SHE ARRIVED IN WEST COVINA. He had been stealing her underwear, her socks and had pictures of her sleeping. Trent actually was testing if she was really in love with him, but what if he wasn't testing her?
- Rebecca's attempts to deal with a yeast infection by just brute forcing more medication are sure to create unbearable Body Horror in any woman watching.
