Here's some scoop on Grey's Anatomy from this week's (Posted on 1/14/14) Ask Ausiello column.

Question: You were on the Grey’s Anatomy set yesterday — what did you find out? —Constance
Ausiello: Well, I stepped foot on several new, potentially permanent sets — one of which will be a major plot point later this season for a longtime couple. Also, something happens in Episode 15 that required Jessica Capshaw to have a stunt double.

Question: Are we going to meet the POTUS that phoned Derek in the last episode of Grey’s Anatomy? —Megan
Ausiello: Nope. He will remain an off-camera presence for the foreseeable future (which means I can continue pretending his name is Fitz Grant).
