Françoise gives a sex education lesson that interests the girls. Alerted by Jolène, Christophe tries to persuade Den to talk to him about his relationship with pornography. Tina visits her parents to ask for their help in finding her biological mother.

Tina explains to Christophe why Edwidge's case affects her so much, as the all-important day approaches for the latter. Anaïs feels very much alone and the news from home doesn't offer much comfort.

Quentin asks Christophe if he can see Edwidge. Morgane tries to make Flora understand the importance of making a real effort with her schoolwork. Tina admits to Christophe that she still feels uncomfortable with Edwidge's choice. She accompanies Anaïs to her first scan.

Caught up in the whirlwind of her emotions, Flora is neglecting her schoolwork and has every chance of failing her year. Tina tries to make her see reason. Den wonders about her new boyfriend who doesn't seem very interested in sex and talks to Christophe about it.

Edwidge prepares to leave the school to live in sheltered accommodation. She warmly thanks Christophe before enjoying a final dinner with the girls and staff. Whilst continuing to sign-up potential sponsors for Tina, her father remains tormented by her insistence on finding her mother.

Flora prepares to return to live with her parents. Den gets to know Bruno, who has a somewhat unusual lifestyle. Christophe, worried that she's heading into a toxic relationship, makes an even greater effort to keep in touch with her.

As Den's due date approaches, Françoise notices once again the extent to which the young woman has a ruthless attitude towards her body. Tina and Christophe worry about her and have every intention of keeping a close eye on her.

Tina tells Christophe that Camille's emancipation request will be heard shortly. They still haven't managed to contact her mother. Tina invites Jolène to recount her story to businesswomen susceptible to help the school.

Den, who has gone back to the chaos of life with her family, asks Tina to take the necessary steps so that she can return to the school whilst waiting for sheltered accommodation. The legal decision concerning her request for emancipation is explained to Camille.

The all-important day is just around the corner for several students. Tina makes even more effort to try to contact Camille's parents, who's very insistent that her father must be present. Thomas comes to Montreal to be with Anaïs.

Christophe tries to encourage Tina, thoroughly shaken up by all that's happening in her life. Julie's lawyer pays an unannounced visit to the school to plead her cause. Camille with her baby and her father call in to say hi to Tina.

It's the start of a new school year. Riliana begs Tina to let her return to school, saying that she is now clean and completely off drugs. Tommy tells Christophe about Anaïs's condition.

Christophe is called to an emergency at his sister's detox centre. On returning to the school, he tries to make Riliana realise the importance of putting all her heart into her work if she hopes to recover her daughter one day. He then witnesses the gulf that separates Éloize's parents.

Éloize's inappropriate behaviour continues to be a problem at school. Christophe does his best to persuade Riliana to continue on the right track despite all her doubts. Tina has to come into school at the weekend to handle an urgent admission request.

Tina has contacted the "Retrouvailles" association, in the hope of finding her biological mother. She is brought up-to-date on the investigation into Jolène's death. Anaïs's behaviour remains a mystery to her family and particularly to Tommy.

The school finds itself embroiled in an ever-worsening battle between Éloize's parents. Social services try as best they can to defend the young woman's rights. Tina tries to make Audrey understand why she hasn't heard from Vivianne.

Christophe remains very concerned about Méli and asks Annie to help him make her see reason. Éric is completely lost and can't understand his wife's attitude. Vic disappoints Sassan by reminding her that she prefers to stick to just being friends for the moment.

The ordeals experienced by each of the girls end up affecting life at the school. Audrey is still worried that Viviane will betray her secret. Éric pays a visit to the school and is pleased to see that his daughter is becoming more mature in contact with the others.

Christophe and Tina wonder whether or not Charlotte should have an abortion. Christophe encourages Vic to talk to him about her experiences with Sassan. He manages to find the right words to persuade the latter to put her trust in him.

Charlotte continues to be a source of worry for the school. As the teenager obtains an emergency appointment in psychiatry, Tina realises that Alexis feels no compassion for her.

Tina and Carolle arrange to meet Sassan's mother to find out more about her younger sister. Still worried about Charlotte, Christophe makes another attempt to interest her mother in what happens to her.

Still without news of Charlotte, her mother comes to the school to meet Christophe. Riliana encourages Éloïze, who's continuing to become more self-confident, to stand up to her mother when she needs to.

The sister of Charlotte's father visits the school to meet Christophe and recount her story. Tina sees at firsthand how at a loss Vivianne appears when facing her parents. She's surprised by one of her friends arriving at the school without being invited and insisting on seeing her straight away.

Tina is present during a particularly unpleasant meeting between Vivianne and her father. Christophe tries to help Charlotte to overcome her deep-seated unhappiness. Méli does her best to help her friend see things in a different light.

Julie arrives at the school without warning, in the hope that Christophe will come with her to the hospital where she has to collect one of her daughters. Tina encourages Riliana, who has to persuade her social worker that her plans for the future are feasible.
