The upcoming "Grey's Anatomy" music event promises to be heart-stopping for the fans and possibly for one of our favorite characters: Callie ( Sara Ramirez) along with her unborn baby.

On Thursday's (March 31) episode, we join Callie and Arizona ( Jessica Capshaw) after a horrible car accident. 

"So, before you can even figure out why it is that she asks Callie to marry her," Capshaw tells TVGuide.com. "They're in this horrible situation."

"I don't know how anybody survives that," Ramirez tells the site. "But, I'll tell you something: It's a wake-up call of epic proportions for Callie. What lies in front of her [after the accident] is more than just glass. It's an opportunity to fight for her life and to make sense of why her life, and her life with Arizona, is worth fighting for, if that's the case."

Watch a preview of Ramirez singing Snow Patrol's "Chasing Cars" and Capshaw singing lead on The Fray's "How To Save A Life":

Note: This video will expire on April 1.
