We are just one day away from the next installment of Grey’s Anatomy, and this one’s gonna be a doozy. In Season 10, Episode 17 — “Do You Know?” — we get to travel down the path Cristina (Sandra Oh) decided not to take as she imagines what her future could have looked like had she made just one decision differently.

From the promo we’ve already seen, it looks like Cristina imagines her life with Owen (Kevin McKidd) and without him. Not surprising, since she and Owen have been kinda sorta (but not really) back together, and Owen very clearly wants her back. Now that Cristina has to make the call, she’s got some serious deliberating to do.

And in a new sneak peek, we see Cristina arguing with Owen in a smackdown we’re really glad we’re not a part of — and they’re interrupted by Jackson (Jesse Williams), who appears to be nursing an arm injury.

Cristina and Owen argue about “reopening” an old conversation. Owen wants to talk about something they’ve closed the book on in the past, and Cristina’s really not having it.

“There is nothing left to talk about,” Cristina tells him. “Owen, I was clear about this. I was so clear. I can’t give you more than what I am already giving you. And if now you need more, get it somewhere else.”

Yikes! The promo doesn’t tell us exactly what the on again, off again couple is arguing about; but if we had to guess, it sounds like the baby thing is coming into play again. In which case, we’re Team Cristina on this one — she’s told him at least 100 times that she’s not willing to budge on living life child-free, and that if Owen wants children, she’s not the right person for him. But judging by Owen’s reaction, he’s not getting the message.

And the real question here: How in the world did Jackson hurt his arm? Only 35 hours left until we find out for sure!
