On Hannibal Season 3 Episode 2, we revisit the scene where Hannibal Lecter leaves Will Graham and Abigail Hobbs for dead. Will wakes up in a hospital, where he is visited by Abigail.
Will recalls a conversation with Hannibal about the Cappella Palatina in Palermo, Italy, and figures that Hannibal would have gone there after leaving Baltimore. Eight months after being left for dead, Will takes Abigail to Palermo, only to find one of Hannibal's sculpted corpses in the chapel shortly after their arrival.
Will is questioned by the police, and makes an ally in Florentian Chief Investigator Rinaldo Pazzi, who shares the same gift for empathy and criminal profiling. Pazzi reveals that he had encountered Hannibal 20 years ago, in Florence.
Hannibal was dubbed "Il Mostro: The Monster of Florence", and was known for leaving his murder victims in the artistic poses of the Italian renaissance painting, "Primavera." Pazzi confronted Lecter, but no evidence was found to convict him, and an innocent man was instead convicted for the crimes.
Pazzi takes Will back to the crime scene, where Will figures out that the sculpted corpse signified Hannibal's broken heart. During his profiling, he is overcome by the image of the corpse sprouting Wendigo features and coming after him.
Will is startled out of it by Abigail, with whom he continues to converse. However, it is revealed that Will was willfully imagining Abigail, and that she had died at Lecter's house. Unbeknownst to everyone, Hannibal watches Will from the balcony of the chapel.
Will realizes that Hannibal is still in the building, and he goes down to the catacombs to find him. Pazzi follows, but Will convinces him to leave for his own safety. Hannibal stays out of their sight, but Will calls out to him, and tells him that he forgives him.
