Grey's Anatomy returns January 6 with an all-new episode, "Disarm." We posted a photo gallery from that earlier. Now here are images from the following week's "Start Me Up."

The synopsis for the January 13 episode - in which Arizona tries to reconcile, but Callie has some "big news to share" - is what has a lot of fans wondering if Callie is pregnant.

The promotional photos below don't offer any real hints there ... we think. This first one makes you wonder! In any case, here's a glimpse of what "Start Me Up" holds for us.

Check out the pics and comment away!
