- Heartwarming Moments: In the final episode of the first season, Leo's master Verocchio (who has spent the entire series complaining about Mac hanging around his studio distracting the apprentices) takes his badly injured servant to Mac's home. When Mac has to go and help Leo, Verocchio says he'll make sure nothing happens to Mac's street kids.
- Magnificent Bastard: Piero de' Medici
