On the Teen Mom 2 episode ‘Last to Know’, while Jenelle Evans finally reveals to everyone that she is pregnant, and Leah Messer takes the girls to California for a vacation, Kailyn is at home dealing with the repercussions of her argument (in front of the kids) with Javi. Kailyn’s other ex, Jo, comes over to talk to Kailyn about the situation. Kailyn admits that in retrospect, their son Isaac should have spent the weekend with Jo the weekend Javi came home. Isaac told his father Jo that he was upset after their fight.
While Jo tells Kailyn that he’s going to have a talk with Javi, too, he warns Kailyn: “Just so you understand, this can’t happen in front of the kids.” Kailyn says, “I know.” Jo reiterates his point by saying: “You can break them. This is, like, make or break.” Teen Mom 2 airs Mondays at 9pm on MTV.
