Kevin McKidd directed this week's episode of Grey's Anatomy, "Don't Deceive Me (Please Don't Go)." We've already seen photos and clips from the February 3 installment.

Now, the actor who plays Dr. Owen Hunt is offering some additional teasers for tomorrow night. For one, he says that at last, Callie is going to crack under the pressure.

“[The scenes are] dramatic and quite light,” he told TV Line. “Basically it’s Callie’s moment to have kind of a meltdown. She hopes Mark and Arizona can work together."

"She hopes that they can both be in her life, but she’s anxious. She has these hormones flying around inside her, like pregnant women do, so she ends up driving her OB doctor [played by Rachael Taylor] to distraction, with very funny but also touching results.”

As for Cristina, McKidd says fans will see “her old scrappy self” this week. That means peeps best get out of the way. “She’ll do anything to trample anyone in her way to get into the OR and cut and get blood on her hands ... It’s fun to see her back to her old tricks!”

As for when he and Cristina will catch Seattle Grace's baby fever?

"They rushed into their marriage at the start of the season, and the conversations they never quite had on fundamental things about life, not just children, are going to start to creep back in," he told TV Guide. "There are going to be some bumps for them."

Do you see an Owenstina baby in the forseeable future?

Will Calzonasloan's odd arrangement possibly work?

Sound off on these Grey's Anatomy teasers below.
