Tous accros aux smartphones?

Cécile and Max share a delicious cake and offer a slice to Mathieu, who is engrossed in his phone. When he doesn't respond, Cécile and Max eat his slice. Mathieu is disgusted! He spends too much time on his smartphone, and goes to ask Grégoire, a professor of developmental psychology and screen specialist, for advice on how to be less addicted to his smartphone. Cécile wonders how the voice, photos, and messages we send with our phones travel. She decides to leave the cabin and follow the journey of the messages she will send to Max during the show.
