Now that the dust has settled from the “save the hospital” drama, Grey's Anatomy Season 9, Episode 18: "Idle Hands" is focusing on the real drama at hand: Derek and Meredith’s baby, of course.

If you can’t wait until the episode airs tomorrow, March 21, to find out what happens with Mere’s dark-and-twisty paranoia and McDreamy’s valiant reactions, have no fear — we’ve rounded up all of the juiciest spoilers about the episode right here so you can prepare yourself for what happens next.

Derek and Meredith discover the sex of their baby — and name him or her! In one of the latest sneak peeks, we see MerDer in bed talking about their bun in the oven. While the three names they’re choosing from are unconventional, we’re sure they can solidify one once they find out the sex of the baby, which is also happening in this episode.

Cristina will take care of Meredith’s baby in a surprising way. It’s not all good news for the couple in this episode. Meredith drives Derek a little McCrazy when she goes into paranoid mom mode and thinks her baby is going to be born with two heads and four legs, and proceeds to spread her Debbie Downer mood to Cristina and Alex in this sneak peek clip, questioning if her child will be born will all sorts of horrible, rare conditions. Thankfully, Cristina offers to “fix” (aka operate on) Meredith’s baby if anything happens; Alex also works to calm her down by proving how unlikely the illnesses are; and Derek will do something “incredibly sweet” to calm his wife’s fears.

Callie and Arizona end their dry spell! It’s been a long time coming for Calzona, and it looks like they’re finally going to do the deed. In this sneak peek clip, Arizona casually mentions that she’d like to cook dinner for Callie and then have “sexy time.” However, before they can plan anything big, Bailey interrupts, which leads us to...

Bailey has big plans that no one will listen to. We know that Bailey is unhappy with the current status of the hospital. She’s not in power; Jackson is in charge; and no one is listening to her. After both Jackson and Cristina dismiss her and her new “project," she tries to go to Callie and Arizona, but unfortunately, she’s a victim of bad timing. We’ll likely learn all of the details about her new idea, but it sounds like she mentions a genome project in the Canadian promo.

Alex tries to woo Jo. Though Bailey is being ignored, the same can’t be said for Jo! Though Alex has kept quiet about his feelings, according to the synopsis, he’ll “give Jo’s new boyfriend a run for his money” on tomorrow’s episode. Sweeping romantic gesture? That isn’t the Karev we know, but it sounds like we’ll love him almost as much as Jo will. (Well, hopefully.)
