A new promo for the episode opens with Nathan showing up at Jenelle's house to discuss a game plan to move forward. "Obviously I wouldn't be here if I still didn't care about you, but we do need to come up with a game plan to stop the feud and stop all the madness and violence," he says.

"So, why did you go to the police?" Jenelle asks. "I never pressed charges in the first place. You don't understand that," Nathan tries to explain. However, Jenelle is in no mood to believe him and points to the police report that says she walked in and attacked him, and that he showed the police the marks of the attack on him.

Nathan explains his side of the story --- he just wanted a temporary restraining order, until she calmed down. "Until I calm down? How am I supposed to calm down when you bring that girl here to pick up Kaiser?" she replies. Nathan responds with, "I want to move forward, I care about you. I am done fighting with you."

"I just don't know what I feel right now. If you come back..." but Nathan cuts her off and says, "I knew who I would choose the whole time ago, it was not a freaking competition for me. You just need to change her attitude."

"Then why do you need her there?" replies Jenelle. "Now you are going to get upset because she is an awesome girl" says Nathan about his present girlfriend.

The episode will also see Leah Messer getting out of rehab but getting cold feet meeting Corey Simms. The promo video opens with Leah driving with her cousin Chastity and her friend Brianna to talk to Corey about their issues. "I'm just so nervous. I hope I'm ready for this conversation," Leah says, as her entourage encourages her to meet Corey and sort things out.

As soon as she parks the car, they notice Miranda sitting at another table. "She is sitting right there. Why can't she sit in the car?" Chastity says. "This is f****d up. I am not doing this conversation if Miranda is here," says Leah.
