More revelations are set to come undone in "Grey's Anatomy" season 12 episode 15, titled "I Am Not Waiting Anymore." According to the synopsis from Cartermatt, Jackson (Jesse Williams) will finally learn that his ex-wife April (Sarah Drew) is pregnant and that the child is his. 

The previous episode focused on the history of their relationship and it only appears that this upcoming episode will delve into their potential future. While it is unlikely that Jackson and April will be getting back together anytime soon, having a child may force them to communicate with each other more often than desired.

However, the title does not just refer to Jackson and April's relationship status as it will also refer to Meredith's (Ellen Pompeo) decision to begin dating again. As previously reported, the character only dated other men briefly during the first three seasons of the show and had stopped dating ever since she became steady with Derek (Patrick Dempsey). 

While it is unclear at this point whom Meredith will be dating, many fans speculate that she will initially try going out with Dr. Will Thorpe (Scott Elrod), a military doctor. The two previously had a brief encounter when Meredith was at the military hospital. Many also point out that Meredith may date newcomer Dr. Nathan Riggs, played by Martin Henderson.

Alex (Justin Chambers) will also be leading a team of doctors as they work on an exhausting operation that involves three different organ transplants. Unfortunately, the synopsis does not reveal how well this operation is going to go and it is always possible for an operation this complex to fail. 

Lastly, the synopsis also reveals that Andrew (Giacomo Gianniotti) does not want any form of special treatment, particularly now that he and Maggie (Kelly McCreary) have gone public regarding their relationship.

"Grey's Anatomy" season 12 episode 15 airs this March 24.
