Le secret de M. Ronchon

Melle Potin, the journalist, wants to do an article on Julia, a newcomer in the residence. To do this, she needs information about her native island and information contained in a book belonging to Julia's mother.

Julia and Sam have to look after Ben, Sam's little brother. A game of hide-and-seek is launched in the residence.

About to knock on her door, Sam overhears Julia talking to her 'best friend'. Isn't he Julia's best freind? Concerned, Sam discreetly investigates.

For the Grande Voisinade, each resident brings a square that best represents him or her, and which will join the year's large patchwork. Julia discovers this ritual a little late and tries, with Sam's help, to bring her square on time.

Convinced that the gift in her mom's cupboard was meant for her, the impatient Julia tries, with Sam's help, to find out what's in the package. But was it really meant for her?

Sam and Julia plan to play in their secret lair, but Tonio wants to find out where it is! It's going to be a tricky one. And what if this new game turns out to be even more fun than the one they originally planned?

Julia has misplaced her lucky seashell, brought back from her island. Sam helps her find it.

Sam has misconceptions about Julia's life when she was on her island. She will try to help him better understand by immersing Sam in a tropical simulation, recreated at the Residence.

A butterfly has entered the residence and can't get out. Sam and Julia try various strategies to capture it and finally set it free.

There are disturbing noises in the residence, like small explosions. Where could this be coming from? Sam and Julia investigate.

Sam is a very sore loser. His friend Julia sets out to help him change his ways. A training program that Sam agrees to follow, even if... it isn't easy.

Invited to Sam's house for lunch, Julia makes a stain on the tablecloth. Sam and Julia don't have much time to wash the stain and fix her 'big mistake'.

Sam has never left his home and dreams of traveling the world. For Julia, on the other hand, home is the world she knows least about. What if they were to play at traveling there together, as if they were circling the globe?

Julia wonders why her mom keeps her presents in the cupboard, while Sam's mom displays them in the living room.
