- Jane saying happily, "You mean, all this time we could have been friends?" She was only Becoming the Mask that she was convinced of thanks to Blanche's lie. Made worse by the fact that Blanche would never have been friends with her even if she didn't try to kill her.
- There is a scene where Jane reminisces about her old vaudeville act, singing her trademark song and reciting poetry with a childlike expression on her face to a Baby Jane doll. That's until she catches a glance at her reflection and breaks down in tears. Despite her behavior up to (and past) this point, you realize that, mentally, she's just a little girl that has never been allowed to grow up, is now realizing that those days are long past and doesn't know how to grow past that. She will always be Baby Jane and that's heartbreaking.
- Blanche gets wistful as she talks about what Jane was like as a child. She says "it wasn't that she was pretty; she was just so alive". This seems to imply that the sisters may have been close before Jane's stardom.
- That's often true for many of the child performers in the days of vaudeville - Judy Garland for example. Pushed into it by their parents and never allowed to have a proper childhood. The father is completely responsible for how Jane turned out, and indeed Blanche too.
- In the opening, after Jane has made a spectacle of herself in front of all her fans, she draws the attention to Blanche (admittedly in a weirdly nice way of demanding Blanche have some ice cream too). Blanche clearly wants to be anywhere else and says she doesn't want any ice cream just to keep the attention off her. Then her father snaps at her when she was just trying to stay out of the way. Her mother finds Blanche inside, sadly watching the other performers.
