It’s no secret that Grey’s Anatomy Season 9, Episode 18: “Idle Hands” is (mostly) all about MerDer’s baby, and in this sneak peek, we see the root of the couple’s problems: Meredith’s intense paranoia.
As a doctor, she knows exactly what can go wrong around her 28-week mark, and she’s even thinking ahead to the many outrageous problems her baby could have once he or she is born. So naturally, she rapid-fire quizzes Alex and Cristina about potential illnesses and problems, and thankfully, Alex shoots most of them down.
Meredith proceeds to spew a lot of medical jargon and diseases, all of which Alex dismisses — save for a few. And Cristina even swoops in to hypothetically operate on her baby, saying, “If your baby has a heart defect, I will fix it,” and “Whatever’s wrong with your baby, we will fix it,” among other perfectly snarky retorts.
However, things end on a sour note with Cristina suddenly walking away. But to find out what happens, you’ll have to check out the sneak peek above.
Catch the next new episode of Grey’s Anatomy on Thursday, March 21, 2013, at 9 p.m. ET/PT on ABC.
