Some of the guest actors' stories work better than others. So the Monica Bellucci episode was incredible (if a little far-fetched) while Sandrine's story here sags a little and she comes across a bit annoying (although cute at the end).
On the other hand, the main characters' stories are superb in this ep, with huge developments for Mathias, Camille and Noemie.
