Cristina found out if she received the coveted Harper Avery Award on the latest episode of "Grey's Anatomy."

In "Go It Alone," Cristina (Sandra Oh) is doing everything she can to avoid writing the speech she'll have to give if she wins the Harper Avery Award.

Meanwhile, Meredith (Ellen Pompeo) asks Derek (Patrick Dempsey) to pick up the kids, but he decides to pull all the interns on a surgery he had cancelled, and absentmindedly forgets to pick up the children. After Meredith's fury subsides, she and Derek have a discussion and agree that they are both juggling too much at once.

Callie (Sara Ramirez) and Arizona (Jessica Capshaw) reconnect after taking care of Meredith and Derek's children and talk about who will carry their next child.

They have a coin toss, which decides that Callie will carry their baby.

Newlyweds April (Sarah Drew) and Jackson (Jesse Williams) have a major argument over religious beliefs. Jackson tells the religious April that god doesn't exist, and she becomes irate and tells him that she "pities" him.

She temporarily leaves the house, and asks to stay at Callie and Arizona's.

At episode's end, Cristina arrives at the Harper Avery Award ceremony, all alone and completely panicked. She calls Meredith to ask her to come, but when she gets inside, she finds that Meredith is already there and Owen (Kevin McKidd) is on his way.

The award winner is then announced--and it's not Cristina.

On the next episode, "Change of Heart," "The doctors receive bad news from Jackson. Meanwhile, Amelia arrives in Seattle for an unexpected visit; Richard heads to Boston to surprise Catherine; and Bailey makes a bold decision after growing disappointed with the lack of progress in her research."

Watch the promo below for "Change of Heart," which airs Thursday, April 24 at 9 p.m. EDT on ABC.
