In the coach, Marc asks Alice if he can put on some music, and when she replies, it's 10:07 on her phone. When Marc puts the music on, the clock behind him says 1:04. On top of that, a few shots later, the clock suddenly goes from 1:05 to 1:08.
Right after the Mayanne/Sylvain scene with Alice in the dorm, Ludovic takes Sylvain's hand, as Alice is getting ready to set up a beige checkered quilt on a bed. A couple of shots later, the quilt is perfectly set up on the bed when Céline arrives with the linen in a blue basket, and then Alice is seen setting up the quilt right after.
When Céline and Alice are talking outside at night, Alice is fiddling with a nearby flower and removing its petals. The flower goes from no petals to full of petals several times.
The swastika-looking pottery is held one way when the camera is behind Alexandre, and the other way when it's behind Sylvain.
When getting into the coach early in the movie, in the establishing shot, Marie and Alexandre are a few meters ahead of the rest of the group. In the next shot, Alice and Ludovic are right behind them.
When Alice, Sylvain are going shopping with the car, and Céline and Orpi are talking about the meditation class near the outside table (it's the same scene), the crew lights can be seen reflected on Alice's and Orpi's glasses.
