Grey's Anatomy: Coming Up In The Hiatus Finale

It looks like next week's episode of Grey's Anatomy is the final new one before the winter hiatus, and here are a few quick tidbits from Grey's boss Shonda Rhimes who tweeted about what is coming up in the (presumably) hiatus finale:

@shondarhimes: Next week's GA episode about to be locked! It has a crazy cliffhanger ending!

And a spoilerish tidbit on Cristina and Owen:

Q: Are u going 2 have Owen/Cristina move on like nothing happened? He has 2 have resentment issues.

@shondarhimes: He does. It's coming.
