On Teen Mom 2 Season 5 Episode 15, the fab four continued to confront difficult situations that left their emotions frayed and their lives on the brink of chaos.
Leah's daughter Ali continues to cope with symptoms of muscular dystrophy which are now preventing her from attending school and threatening to keep Leah out of work.
Speaking of jobs, Kailyn is worried about being alone for four weeks while Javi leaves town for job training. Meanwhile Chelsea is having training issues of her own, as she's forced to take a temporary hiatus from work until she's receives her proper licensing.
And while the other girls struggle, Jenelle Evans, of course, continues to experience enough drama to sustain a dozen reality shows.
The breach of peace charges against Jenelle have been dropped, but her boyfriend Nathan Griffith is still facing 30 days in jail. Jenelle's mom, of course, seems downright thrilled with the prospect of Griffith getting locked up.
Despite troubles in her professional life and her continued guilt over baby daddy Adam's absence, Chelsea is moving forward admirably - somehow holding down her job despite lacking the proper license and moves into her new home.
But while Adam Lind may hold the title of Teen Mom's worst dad, the other guys seem determined to give him a run for his money.
Nathan prepares to begin serving his jail sentence ahead of schedule (which totally interrupts his bender), while Joe skips Isaac's birthday party so as to avoid making his new girlfriend uncomfortable.
As the adults cope with primarily self-created problems Ali Messer continues to suffer through no fault of her own. In seemingly constant pain and soon to be reliant on a wheelchair, little Ali watches her rambunctious twin bounce around the house without any real understanding of why she can't do the same.
There's always plenty of real human drama on Teen Mom 2, but Ali's situation reaches the level of full-fledged tragedy.
