Alba Villanueva

Alba is Jane's devoutly Catholic grandmother, the one who instilled in her the vow of purity that gives the show its title. She keeps the Villanueva household warm and watchful, ready with wisdom, superstition, and Spanish asides. Fiercely protective and quietly formidable, she's the moral anchor around whom the family's chaos orbits.

Ivonne Coll plays Alba with a dignity that never curdles into scolding — her faith reads as lived conviction, not a punchline, even inside a telenovela's wildest turns. The writing trusts her with real interiority beneath the archetype of the strict abuela, and Coll makes her tenderness as forceful as her convictions.
