The Grey's Anatomy drama is stretching to a breaking point as we hurtle toward toward the midseason finale next week. And in the penultimate episode of 2013 tonight, December 5 — Season 10, Episode 11, "Man on the Moon"Cristina (Sandra Oh) will finally commence the experimental operation she pursued at the expense of her friendship with Meredith (Ellen Pompeo).

The show's official Instagrammers posted this image yesterday, December 4, writing: "The fate of baby Nathan lies in Cristina's hands on tomorrow's all new episode of Grey's Anatomy. [Like this image] if you think her surgery will be successful!"

That caption implies that Cristina will finally be putting in the artificial graft into the newborn's heart — the one for which she and Shane (Gaius Charles) have monopolized Meredith's 3D printer.

If her surgery isn't successful, the saga will conclude with an Alanis Morrisette-level of irony. All that work and all that strife with Meredith will be for naught.

But at least she'll have gotten closer to Shane. When he yelled at Meredith in Cristina's defense last episode, our fave heart surgeon realized that she not only had a "sex toy," she had a true teammate and advocate.

And we all know Grey's Anatomy is not afraid to kill off "tiny humans." Nathan, we're pulling for you, but…

Do you think the little guy will make it? Or will Cristina's efforts go in vain? Speculate away below!
