Grey's Anatomy season 11 episode 10 synopsis out: Will Jackson and April lose their baby?

Grey's Anatomy mid-season premiere saw Derek leaving for Washington DC, but he was going to make his relationship with his wife work.

Another important revelation in the episode was Jackson Avery (Jesse Williams) telling his wife April Kepner (Sarah Drew) about their unborn baby's condition, and both of them freaking out over the unexpected news.

In season 11 winter finale, it was revealed that the duo's child had osteogenesis imperfecta, meaning that their baby would be born with brittle bones.

Next week's episode is titled, The Bed's Too Big Without You, which will air Thursday, February 5, 2015 on ABC.

According to the official synopsis, "April stays optimistic as Arizona begins testing on her baby; Dr. Herman plans out a crash course in fetal surgery; and Owen and Callie encourage each other to get back into the dating scene. Meanwhile, Meredith, Maggie and Bailey use the 3D printer to gain a better understanding of their patient's tumor."

A new promo shows April and Jackson arguing about their baby's medical results and what to do next.

Jackson says, "So I think we need to talk, what will we decide if the baby is Type-2?"

April replies, "I already told you he won't be."

Jackson argues that if their baby is Type 2, which is terrifying, they needed to talk about it, and plan ahead.

But April disagrees, "I don't talk about it, why cannot we wait till tomorrow."

The couple argues about what to do next, as April accuses Jackson with, "You already know what to do, just say it out loud."

Previously, show creator Shonda Rhimes told Entertainment Weekly that the baby's condition will cause Kepner to wrestle with her religious faith.

In the preview for the February 5 episode, Kepner and Avery are getting some sort of test done on the baby that will make them "consider the unthinkable."

When Drew pitched the storyline to Rhimes, she teased, "We thought that Kepner's struggle will be dealt with in a beautiful way for such a strong Christian character and what this situation will do to her faith."

Considering Kepner's deep religious views, could the show be setting her up to have to think about getting an abortion.

Previously, Camilla Luddington who plays Jo Wilson teased that even the cast members were crying during the filming.

"There's no relaxing. There's no calm before the storm. It's just storm. All storm, all the time," she told TVLine.

Does this big storm and crying scene involve April and Jackson's baby?
