On Grey's Anatomy Season 9, Episode 22: "Do You Believe in Magic?" Owen (Kevin McKidd) assured Cristina (Sandra Oh) that he doesn't want kids. Even so, he's clearly become very attached to Ethan, whose parents were fatally injured in the oil tanker explosion, and in this sneak peek for Season 9, Episode 23: "Readiness Is All," the fate of Owen's young friend is more unsure than ever.

In this sneak peek of the episode, Cristina tells Owen that Ethan's grandmother wanted to talk about withdrawal of care for Ethan's father, who isn't getting any better. Owen freaks out about this idea. What will he do if Ethan's father dies? He already lost his mother.

Here's the official synopsis of the episode:

The doctors of Grey Sloan Memorial Hospital prepare for a super storm heading towards Seattle; Owen’s desire to be a parent gets stronger as he becomes closer to Ethan; and one wrong move puts the lives of Meredith and her baby in jeopardy. Meanwhile, Jo looks to Alex for help in a moment of crisis, and one doctor gets the shock of her life.
