April Kepner's (Sarah Drew) anger toward Jackson Avery (Jesse Williams) will be heard all over Grey Sloan Memorial Hospital in the next episode of "Grey's Anatomy" season 12.

In a sneak peek for the episode titled "Unbreak My Heart," viewers can see the very furious April as she confronts Jackson for being served with the divorce papers in their workplace.

"What does it matter how loud my voice is when 35 people just saw me get served with divorce papers in the middle of the emergency room?" April yells as Jackson tries to make her lower her voice.

April wants to know when ackson decided that he could no longer stand being married to her, since he agreed to go through marriage counselling to save their relationship. But Jackson says that it is not working anymore.

"It didn't work. It didn't get us anywhere. We have the same exact fight over and over again, in circles. I'm telling you it's not working."

But while the couple is seen fighting in the sneak peek, the entire episode will also offer flashbacks that feature the highs and lows of their relationship. It includes the day that they first met at the Mercy West Hospital, their wedding date, as well as the time when April decided to re-enlist herself to serve as a medical staff in Jordan after their baby died.

The official synopsis for the episode reads:

"The evolution of April and Jackson's relationship is revealed through a series of flashbacks dating back to when they first met. Simultaneously, we follow the years-long progress of one of Jackson's patients."

The episode will also feature the return of Jackson's mother Catherine, portrayed by Debbie Allen. Could she help the couple patch things up?

"Marvel's Agents of S.H.I.E.L.D." star Maya Stojan will also join the show as Jackson's patient in the upcoming episode, which will air on Thursday, Feb. 25, on ABC.
