April had been a big part of Chicago Med since its series premiere. And her on-again, off-again relationship with Ethan was part of her storyline in Season 6.

At the end of the season, Ethan recovered from a gunshot wound and April confessed that she still loved him, which was a big moment for fans who still shipped them as a couple. It seemed like that moment meant they would be back together for good once the show returned for Season 7.

Unfortunately, the relationship wasn't meant to be. In the Season 7 premiere of Chicago Med, it's revealed that April is away studying at a nurse practitioner program and Ethan is undergoing physical therapy following his near-death experience.

And it all has to do with some behind-the-scenes complications. Yaya DaCosta, who played April for six seasons, spoke to TVLine about her character's abrupt exit from the show.

"I think that when [the finale] was written, the idea of April not being at Gaffney Medical Center, and me not being on the show, was not even a thought," she shared. "Things happened behind the scenes very quickly. We were literally in the final days of shooting the episode while conversations and negotiations about my working there were going on."

During a September 2021 Television Critics Association panel discussion for Our Kind of People, which Yaya was cast in following her Chicago Med exit, she said the timing was just right.

She explained that "there was a window" during which her fate on Chicago Med was unsure and in that time, she "fell in love with Our Kind of People." For her, it made sense to move on from the medical drama.
