Guillaume finally calls Adèle back, and they set out to look for their father in his usual haunts. Will they find him?

Adèle's relationship with her mother is at an all-time low. Still, she's determined to meet her father. However, her meeting with her half-brother Guillaume doesn't quite go according to plan....

Lionel is at a local market in Toul near Alsace, where he samples a beer from a local micro-brewery that sells its products at several markets in the area. The beer goes by the name of "Coin Coin" ("Quack Quack") for no other reason than catching people's attention. The young lady, who brews the beer herself, reassures Lionel that consuming her beer will not give him webbed feet...

Adèle discovers the whole truth about her dad and the tragic circumstances that led to his forced disappearance. Her mother's attempts to sugarcoat the truth do little to appease her anger.

Adèle's half brother Guillaume approaches her outside her workplace and introduces himself. After a brief talk, she agrees to meet him again.

In the last part of his tour of L'Isle-Adam, Daniel takes us to the town's glassblower, who offers introductory courses in his beautiful artform. He also shows us the L'Isle-Adam ponds (which act as a sanctuary for over 150 bird species) and the mysterious Chinese pavilion, the architect and construction date of which remain unknown.

Adèle's mother tries in vain to keep the truth from Adèle, who found out her father might not be dead after all. A surprise visit complicates things even further.
