- Though it's also a Bittersweet Ending, the relationship between the narrator and Maxim after the events of the novel. Though they're in hiding, they're at least content.
- The musical makes it less bitter because it's implied that they're not in hiding: Favell notes that the jury won't make a murder suspect out of the Honorable Mr. de Winter unless they have clear proof. The Reveal that Rebecca committed suicide (the audience knows it's Suicide by Cop via a fall, the authorities think Rebecca sank the boat herself) presumably set Maxim free.
- Maxim's offer of marriage is the least possible, until it becomes clear to the reader that he is really attached to the heroine.
- Generally, Beatrice acts like a Cool Big Sis towards the heroine. When they find out that the dress the heroine wore is the same one Rebecca had for her previous party, Beatrice goes to comfort her sister-in-law, helps her choose a new gown, and explain the context. Even though Rebecca was a homewrecker with Beatrice and Giles's relationship, Beatrice loves the new Mrs. De Winter and understands she's a different person.
- Beatrice's well-intentioned bluntness, and her happiness when seeing her brother happy. Her showing up to see Maxim and Ich through the inquest demonstrates that she genuinely likes and cares for her young sister-in-law.
- The discovery of Maxim's real feelings for the heroine, and the certainty that he loves the heroine more than Rebecca. It gets even more heartwarming when you realize that the hero, terrified either because of fear or remorse, after a marriage to the charming, cruel and selfish Rebecca, met an Adorkable, genuinely in love Shrinking Violet and fell in love with her too.
