If you watched this week's episode of Teen Mom 2, you know there was no shortage of high drama.
In fact, there was so much packed into one episode that the three-way conflict between Kailyn Lowry, Jenelle Evans and Javi Marroquin threatened to overshadow one of the series' most intense scenes to date.
Longtime viewers know that Leah Messer's daughter, Ali, suffers from muscular dystrophy, which has resulted in numerous complications over the years.
On last night's episode, Leah received a nightmare phone call from her ex, Corey Simms, informing her that Ali needed to be rushed to the hospital efter experiencing breathing difficulties.
"The reason I am calling is because Ali is having a hard time catching her breath and I think I need to take to her to emergency room because she says she couldn't breathe," Simms informed Leah.
"She's fine...I think it's a little scarier for us. But we'd rather be safe than sorry."
Naturally, Leah rushed to the emergency room to be certain that Leah was well taken care of.
Sadly, respiratory problems are no surprise for the family, as they're among the expected complications of Ali's rare and incurable illness.
"The disorder affects her respiratory system and progresses the older she gets," Leah said in an interview shortly after Ali was diagnosed.
"The bigger she gets and the more weight she gains, the harder it'll be for her muscles to carry the weight."
The hearts of millions of fans have broken along with Leah's as they've watched Ali's condition deteriorate over the years.
Fortunately, the 7-year-old and her family remain optimistic about her future health prospects:
Leah took to Instagram after last night's episode aired to assure fans that all is well:
"Muscular Dystrophy won't stop our girl! We always want her to know that if she can dream it, then she can do it! We believe in her like she believes in herself!" Messer wrote.
"We didn't want her to feel different in a special needs class, but if it was in the best interest of Ali Girl, that's all that mattered!"
Fans have expressed heartfelt warm wishes to Leah and Ali, who has served as an insipiration on a series loaded with cautionary tales.
