 I read someone else's post explaining how as Ezio was dying he basically hallucinated himself as a young man there since in the end you get the credits “when i was a young man I had liberty but did not see it, I had love but did not feel it” and so on, plus how the man says courage Ezio, before leaving, and would explain why Ezio confronted him with “I don't think its the women that are the problem”
