Mariano and the Madrigals

Mariano's relationship to the Madrigals after he marries Dolores

 Camilo doesn't trust him

Antonio just thinks "Sweet, extra brother."

Isabela treats him the same way she does Camilo which means pranks and throwing flowers at him, thankfully he never does anything to warrant cacti being thrown at him. Yet.

Mirabel thought the overprotective brotherly nature of how Mariano interacted with her would go away when he was not to become her brother in law, it did not. He still calls her hermanita and Dolores and Isabela just laugh every time.

Luisa is named the babysitter for their kids because he knows she worries about being left alone with small kids, so it's a sign that they trusted her completely for that. It was Mariano's idea, but Dolores quickly seconded it.

Felix is just making sure his daughter is not just a rebound to Mariano

Abuela can't stop apologizing.

Julieta mostly gives her daughter looks of I told you so, and just treats Mariano how she does the rest of the family.

Agustin saw this coming in all honesty but didn't want to say anything because he thought his daughter actually loved him. Now he says Pepa owes him money.

Pepa will not be paying that because they never officially  bet. She also, once she likes him, treats him like her son, and cries enough to warrant a mist when she sees Mariano interacting with Dolores for a while.

Bruno is just thankful the prophecy worked out. Although he remembers it and thinks through it, eventually landing on "Betrothed! The prophecy was betrothed?! Never married...agh! Why didn't I see that coming.
