We don't talk about Bruno. But why?

No no no, we don't talk about Bruno. But-

Okay, like, one major plot point in Encanto is when Mirabel finds the prophecy and her dad finds it, Dolores overhears. And because of her nature she can't help but tell everyone she can. Fine. Whatever. I can buy that. But then near the end of the film, Dolores, the one that can't keep a secret, is all like, Yeah I heard Bruno every day and never told anyone, it leaves you questioning. So can she or can't she keep a secret? 

And Bruno was literally just living in the walls of the house the entire time? Can the house keep a secret then, because casa surely knew, right? 

Anyway. Wait, could Bruno hear everyone singing about him? And why don't they want to talk about him? Because they thought he was evil? Heck, we think Hitler is evil but we still talk about him. The only evil guy that people don't like talking about is Volde- uh, I mean he-who-must-not-be-named. So why don't they talk about Bruno? Because they are ashamed that they ostracized him from society by judging him too harshly? 

By the way, totally head cannon, but I think that Bruno is Alberto's (Luca's friend in Luca) father. Green eyes? The time periods match up? Alberto uses the phrase "Silencio Bruno"? Coincidence? I think not!
