Throughout this season of "Teen Mom 2," it seemed as though Kailyn's current and former loves — Javi and Jo, respectively — managed to get along just fine. But looks can be deceiving. Apparently, after Javi learned about some of his wife's arguments with her ex, he was none too pleased about the way Jo conducted himself.

In this sneak peek of the reunion special, which will air in two parts (tonight at 11/10c and next Tuesday, April 22, at 11/10c), Javi confronts Jo about his behavior, specifically some of the negative comments he made about Kail's pregnancy. (Remember the whole, "I hope your f**king water breaks tonight" dig?)

With Kailyn sandwiched between the two, Dr. Drew explains how important it is for the men in her life to co-parent civilly, because the children can sense if there's tension among them. When he encourages them to talk it through further right then and there, Jo actually does apologize. "I'm sorry for saying that," he offers, leaning forward on the couch to look Javi in the eye. "I was wrong. It was awful, but it happened." However, when Dr. Drew asks if Jo's mea culpa is good enough, Javi responds, "We'll see when the cameras stop rolling." Oof! Sounds like it's gonna be another intense show, folks.

Will Javi be able to forgive Jo for talking smack, at least for the sake of Kail and the kids? Check out the video, and tune in tonight at 11/10c to see how their conversation concludes.
