Mika deals with her sister's cancer in Grey's Anatomy season 21, episode 4 (Preview)

Just as we got a relationship that we could get behind, Grey’s Anatomy has thrown us a curveball. What can we expect in Grey’s Anatomy season 21, episode 4?

Now, let’s be honest, we knew that Midori Francis was leaving the series. That meant we weren’t really sold on the Mika/Jules romance. That didn’t mean we don’t want or need it, but when you announce a character is leaving, we rule out personal connections lasting.

Now it looks like we have that exit storyline. Here’s what we can expect.

It’s all about Mika’s little sister in Grey’s Anatomy season 21, episode 4

At the end of the previous episode, Mika shared with Jules that her sister had been diagnosed with rectal cancer. It’s time to find out how bad that is, especially considering she is only 22. The promo makes it clear that things aren’t looking great, with it being at Stage 3 already. This means there is a little hope, but Mika is terrified.

While all this happens, Bailey and Ben need to figure things out now that Ben is back at the hospital. Bailey got her job back as the head of the residency program, and that means that she is Ben’s boss. What will that do to their personal life? Can they keep everything separated? That’s something that will play out throughout this episode.

It’s Jo and Link’s story that I’m intrigued about when it comes to this episode. They get some “surprising news,” and I can’t help but think that this is going to be that they find out they’re expecting twins. It’s cliché, but this is a drama!

Check out the promo and synopsis for Grey’s Anatomy season 21, episode 4:

"Mika struggles with a life-altering personal matter. Meanwhile, Bailey and Ben navigate their personal and professional roles, while Levi finds a connection in an unlikely place. Jo and Link get surprising news."
