Okay everyone I just had an encanto headcannon.
So whenever Pepa is mad at someone Felix is right there trying to calm her down, he probably wants to deal with the problem the calm way. Not saying he doesn't care that his wife is mad he just doesn't want Pepa to do someone she'll regret.
Agustin however is different. On the rare chance Julieta is mad at someone to the point of giving them a verbal smack down, which is rare, Agustin will be right there being a yes man.
Julieta: I can't believe you would be so selfish
Agustin: Extremely selfish!
Julieta: You're acting like you were raised in a barn
Agustin: Yeah your acting like you were raised in a barn!
Julieta: Agustin, sweetie, I got this. You can stop now.
Agustin: Yeah she's got this!
Julieta: Agustin stop...
Agustin: Yeah Agustin you stop!
Julieta: I love you, but it's clear I didn't marry you for your brains.
Agustin: Yeah she's didn't marry me because of my brai- Wait you didn't...
Julieta: *Long sigh*
