- Dioneo's story causes controversy, so the crew argues and discusses it for a while.
- Panfilo takes the lead in considering what they should do now.
- What they need, he says, is to keep perspective: remember where they came from, what they're doing here, and decide what should happen next.
- He concludes that they've done a great job in behaving themselves and having fun, but that if they stay longer, they'd get bored and people might talk.
- Plus, lots of people know they're here and might show up and ruin the fun.
- So, in his humble opinion, they should head back to Florence on the next day unless anybody objects.
- No one does. They continue with their regularly scheduled evening amusements, featuring Lauretta (leading a dance) and Fiammetta (singing the concluding song).
- Fiammetta sings of how jealousy ruins the security and bliss of love. But she's no shrinking violet—she'll put the hurt on whoever steals her love away.
- Dioneo laughs at the warning in the song and tells Fiammetta she should publish the name of her lover so no one accidentally wins his heart away from her.
- In the morning, they get up early and return to Santa Maria Novella, which was the place of their departure.
- The young men go off to find something else to amuse them and the ladies go home.
- Seems a bit anticlimactic.
