Teen Mom 2 is back! MTV's most popular spinoff aired its season 7 premiere on Monday, March 21, and the drama was at an all-time high. Not only did Jenelle Evans face potential jail time for throwing water at her ex-fiancé's new girlfriend, Leah Messer dealt with parenting pressure, and Kailyn Lowry's new friendship with her baby daddy created marital strife. Also, a deranged dog attacked a chair belonging to Jenelle's friend, but fear not, "It's only from Big Lots." Phew.

In Her Words: Jenelle Explains Water(-Hurling) Gate 2015

No love for Nathan Griffith! Jenelle and her ex were barely on speaking terms during the episode, and when they did speak, it was not pretty. Jenelle refused to let Nathan see their son, which led him to say (read: scream), "You can't even get a job because you're a felon and you have felonies!"

So, was Jenelle a felon at the time this episode was filmed? Not so much, but her misdemeanor charges for attacking Nathan's girlfriend were a huge problem. Not only was Jenelle looking at 30 days in jail, she wasn't able to fight for custody of her first son, Jace. "I can't do anything until this charge is dropped because it's a violent charge," she explained to a friend. "I'm so f--king mad because it scars me for life, dude. I've worked so hard to get my life together, and now it's like, if I have this charge, I don't think I'll ever get a job, dude."

While Jenelle claims to have thrown water at Nathan's girlfriend in self-defense, the alleged victim had a different story. "I was just sitting in the truck — just out of nowhere, I just got smashed in my head and covered in ice water," Nathan's gal told him. "You just can't have Kaiser around that ... I hate saying it, if he's more safe with you, I'd like to help build your case."

Chelsea Hates on Adam, the Sky Is Blue

Aubree is all grown up! Chelsea Houska's daughter started kindergarten, and if you're wondering whether her notorious dad, Adam Lind, showed up for the big day, the answer is yes. But, um, Chelsea wasn't thrilled: "Obviously, I think it's good when he shows up for stuff, but I'm not like, 'Whoop-di-doo, you're the best dad ever,' because that would be a lie."

Adam asked Chelsea if she'd be open to changing the restrictive terms of his visitation, and while she seemed pretty on board, she later told a friend that she's not ready for such a huge change. "I think we should give [Aubree] some time to get used to [school] before we even think about anything," Chelsea said. "I'll never trust him. I will always think he's a pile."

Leah Reaches Her Wit's End

Poor Leah! This Teen Mom and her ex Corey Simms were in the midst of a custody battle, and things were all kinds of awkward between them at their daughter's physical checkup. To make matters worse, Leah was having a visibly hard time getting her kids to school on time — something Corey's been critical about in the past.

To be fair, the twins attend school 45 minutes away, which means Leah has to wake up at 5 a.m. every morning. But it was nonetheless hard to watch the single mom send her kids out without breakfast or lunch. "You're always worried about everything else except for going to pick us up and giving us lunch," Aleeah complained in the car. "I'm cold, and I don't have nothing to eat. You never get us up for breakfast."

Leah told her daughters that they could eat breakfast at school, but when they asked to stop at a gas station for lunch, she said they didn't have time.

Kailyn + Jo - Javi = Unholy Matrimony

The honeymoon is over! Kailyn and Javi Marroquin's marriage was pretty rocky this week, and it's all thanks to a budding friendship with her baby daddy, Jo Rivera, and his pregnant girlfriend, Vee Torres. These three decided to get their co-parent on, and Javi just wasn't having it. "I don't care about this," he told Kailyn after she accused him of making everyone uncomfortable. "We're not friends — we don't have anything in common."

Javi ended up ditching a family portrait session because Jo and Vee were there, and then refused to join the group for dinner. "We need to get Javi on board," Kailyn told Jo and Vee. "He doesn't want Lincoln with you guys."

Jo seemed worried that Javi's grudge was personal, but Kailyn assured him that the issue is their own marriage. "Today was just a rough day — we were arguing about other things," she said. "I think that whatever issues, they are stemming from Javi and I. It's not really necessarily you guys. [We went to counseling] last year. I'm more overwhelmed now than ever."

Tell Us: Do you think Javi is being unfair to Kailyn?

Teen Mom 2 airs on MTV Mondays at 10 p.m. ET.
