O Tio Leão e o Nevoeiro: Master Emotional Portuguese & Family Communication

72 years old. Has lived in Porto his whole life, inspired by the city's artistic heritage and the Serralves Foundation. Never married, devoted to art. His sculptures are in major museums across Europe. Spends nights reading about quantum mechanics 'for fun.' Recently forgetting words, repeating stories, getting lost in familiar places.

36 years old, Leão's niece (Alex's cousin). Works in geriatric care. Has seen cognitive decline professionally and now fears seeing it in her beloved uncle.

65 years old, owns a prestigious gallery in the Baixa district. Has shown Leão's work for 35 years. Recently, Leão missed a meeting and seemed confused about a piece he'd created.

67 years old. Leão practically raised her after their parents worked long hours at the textile factory. She owes him everything and the thought of him declining is unbearable.
