I'm not a Grey's Anatomy watcher. Haven't been since season two. But there are certain episodes that I simply can't miss!

• January 19, 2012Will Katherine Heigl Return to 'Grey's?'

The big Super Bowl episode, the armed shooter that ended season six with a two-part bang and musical episodes were all DVR'd in my house.

Katherine Heigl Wants Back on Grey's!

And it looks like next week will see Meredith Grey coming back into my life for one more brief appearance.

Titled, If/Then, next week's episode gives fans a glimpse at an alternate timeline inside Seattle Grace that has all our characters making different life choices.

Which Grey's Star is Pregnant in Real Life?

What if Ellis Grey never had Alzheimer's? What if Meredith had never met Derek in that bar? What if Addison and Derek never divorce? What if Callie and Owen had become a couple long before she met Arizona? What if Bailey never evolved from the meek intern she once was?

These questions and more (WTF Lexie?!?) are asked next week and now you can get a sneak peek at all the alterna-fun!
