The next new episode of Grey's Anatomy, "Don't Deceive Me (Please Don't Go)," airs February 3 and is directed by cast member Kevin McKidd. Here are some photos from it.

Callie, Mark and Arizona must learn to navigate through the pregnancy together, which starts off with Callie driving her new obstetrician (guest star Rachael Taylor) crazy.

Meanwhile, Derek breaks ground on his clinical trial and Meredith feels left out, and Bailey's attempt to integrate social media into Seattle Grace causes friction with Richard.

Click to enlarge the photos below and tell us what you think. Is Arizona okay (or trying to be okay) with the pregnancy? Will the clinical trial lead to more MerDer tension? Discuss.
