April Kepner wants Jackson Avery to be at her wedding, but will he attend the ceremony in Dec. 12 episode of Grey's Anatomy?

Enstars saw a sneek peek clip of the new episode, and the video revealed the answer.

April (Sarah Drew) walks through the hospital in sweats and with hair rollers in her hair before she is stopped by Jackson (Jesse Williams), who asks her what she is doing instead of getting ready for her big day.

"I'm hunting bridesmaids," April furiously responds. 

Though Jackson tries to make light of the situation, a stressed out April asks him "Are you gonna be there?" After a momentary silence on Jackson's part, she adds "I totally understand if you're not I just --"

"Do you want me to be there?" he asks back, to which she replies, "Yes! Of course!"

"Then I'm gonna be there," he replies.

Thursday's episode is titled Get Up, Stand Up. Its synopsis is as follows:

"On the day of April's wedding, the Grey Sloan Memorial doctors are all preoccupied with their own drama. Meredith and Cristina continue to argue about their research and careers, Bailey comes clean to Ben about her feelings regarding him moving back to Seattle, and Shane puts himself in a risky situation. Meanwhile, Derek gets a phone call that will change his life."

April's three siblings made an appearance in the Dec. 5 episode, titled Man on the Moon. They were played by Days of Our Lives' Emily Happe, Drop Dead Diva's Elizabeth Bond and The Middle's Grace Bannon.

April told Jackson (Jesse Williams) in the Nov. 21 episode that she wants his blessing before she married Matthew. He gives her his blessing and then disinvites himself from the wedding. His actions raise Stephanie's (Jerrika Hinton) suspicions: she is wondering why the exes act strange around each other if they supposedly no longer in love. 

April's wedding will take place in the episode that is the series' last before it goes on a winter hiatus. The season is slated to end with the exit of Sandra Oh's character, Cristina Yang.
