As Mirabel's mother and the healer of the Encanto, Julieta needs to be a more diverse character.
First, did anyone else notice how basically all the madrigals had a song except Julieta and Agustin (and Antonio)? Like Pepa and her family had "We Don't Talk About Bruno". Isabela had "What Else Can I Do". Luisa had "Surface Pressure". Mirabel had "Waiting on a Miracle". And Abuela Alma had "Dos Oruguitas". I mean both Julieta and Agustin make appearances in "The Madrigal Family", and "All of You" but they didn't have songs about themselves personally.
Another thing about Julieta is that I think that we need to see her room. Like, for example, I don't know about you people but I would love to see her room. Like a giant kitchen or garden with infinite resources for cooking and healing alike.
I also want her to interact with her other daughters some more. Isabela and Luisa seem to not get very much of their mother's attention. And Julieta hardly ever interacts with either of her oldest daughters.
