"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 told Messer on the phone.
"She's fine," he added. "I think it's a little scarier for us. But we'd rather be safe than sorry."
Ali suffers from a rare and incurable form of muscular dystrophy, and her school has told Simms and Messer that they are concerned about Ali.
The end of the episode saw Messer rushing to drop her daughter Addie off at her grandmother's before racing to the hospital to be by Ali's side.
