On this season of Teen Mom 2, there are a lot of moving parts.
Jenelle Evans, for example, is jumping from being married to Courtland Rogers and having an abortion to dating a new man and now being pregnant with his child.
Chelsea Houska is changing career paths and Leah Calvert is finding herself increasingly frustrated with her husband, Jeremy's job, especially as she deals with her daughter Aliannah has a much more difficult road ahead of her than anyone had anticipated.
Kailyn Lowry is also in transition, marrying Javi Marroquin, pregnant with her second child (she has since had the baby) and trying to figure out how she can move to be with her husband without creating an enormous custody battle.
In this sneak peek from Tuesday's episode, we see the tension coming to a head between Kailyn and her ex-boyfriend, Jo Rivera as their custody battle continues to heat up.
At the end of the conversation, Jo lets his temper get the best of him as he makes a mean comment to Kailyn as she walks away.
Do you think they'll ever be able to come to an agreement...for their son's sake?
