chunk: Tito learns from Fra Luca, a Dominican monk, that his adoptive father has been forced into slavery and is asking for assistance. Tito introspects, comparing filial duty to his new ambitions in Florence, and decides that it would be futile to attempt to rescue his adoptive father. This paves the way for Romola and Tito to marry. Fra Luca shortly thereafter falls ill and before his death he speaks to his estranged sister, Romola. Ignorant of Romola's plans, Fra Luca warns her of a vision foretelling a marriage between her and a mysterious stranger who will bring pain to her and her father. After Fra Luca's death, Tito dismisses the warning and advises Romola to trust him. Tito and Romola become betrothed at the end of Carnival, to be married at Easter after Tito returns from a visit to Rome.
