Jenelle and Barbara had been getting along really well lately, and the way we left off after the TM2 season finale, they were committed to making their relationship work now that Nathan seemed to be out of the picture.
In this sneak peek, Nathan is back sitting next to Jenelle and it looks like the detente between Jenelle and her mom was short-lived.
It seems that custody of Jace is still an ongoing issue, as Jenelle asks her mom how she would feel if her kids were taken away from her. "I would feel terrible, Jenelle, but I would have done everything in my power to get that kid back," she replies.
With that, Jenelle storms off and what she says backstage is even more upsetting. The producers try to convince her to go back on stage and talk things out, but Jenelle isn't having it. "I'm done you guys, I'm done! You're not forcing me to f**king film," she screams, before she exits the studio altogether.
To see if Jenelle ends up coming back or if they're able to eventually talk things out, tune in to Part 1 of the Teen Mom 2 Reunion Special Wednesday at 9/8c on MTV.
