Last week on "Teen Mom 2," Jenelle and her mother tried to sort their issues regarding Jace's custody, Leah left for rehab, while Kailyn demanded Jo to pay more for child support. 

Jenelle and her mom Barbara tried to settle their differences over their issues involving Jace's guardianship, with Jenelle wanting her son to be with her during the week and with Barbara during weekends. But Barbara wasn't having it because she thinks that the boy would be unhappy if he was forced to live with Jenelle. Barbara urged her daughter to be reasonable as she didn't want them to end up in court. 

Meanwhile, Kailyn and Javi met Jo at the park and told him that what he was giving for child support wasn't enough, and she threatened to meet him in court if he didn't give more. Jo asked her if they could work it out without having to involve lawyers. 

After coming home from rehab after her mother told her that she fears she wouldn't get her child back from her ex, Leah went back to the treatment center to get help. Although her daughters were confused about her leaving, she was determined to get better. 

This week, on the Sept. 17 episode of "Teen Mom 2," Kailyn is distraught when Jo goes missing, and Leah ends her marriage to Jeremy. Meanwhile, Jenelle may face felony charges after she got into a fight with Nathan and his new girlfriend.

The incident involving Jenelle was reported last month, and it was revealed that she was arrested for allegedly assaulting Nathan's new girlfriend after Nathan brought the woman to Jenelle's place. She was charged with third-degree assault after she reportedly threw a drinking glass at the victim's head. According to Myrtle Beach Online, Jenelle was released after posting a personal recognizance bond.

"Teen Mom 2" airs Thursdays at 10 p.m. on MTV.
