With Cristina back at Seattle Grace on "Grey's Anatomy," she wasted no time in getting back to what she does best. Namely, scaring the crap out of interns.

Fully reclaiming her title as the queen of mean, she had her latest batch of surgical interns squirming beneath her. First, she declared that she wouldn't be bothered to learn their names for at least a year. Instead, she would call them by their dwarf names, dubbing Dr. Ross "Happy."

But then, a trick! "Now get me up to speed. Every patient, every chart. I wanna know this floor better than you," she said. When Dr. Ross said, "Right," Cristina pulled out the rug.

"Wrong. You’re surgical interns," she said. "Nobody should know this floor better than you." And to Dr. Ross, "You’re Dopey now."

After all her recent emotional struggles after the plane crash and the loss of her mentor and friend, Celebuzz thought it was great to see Cristina back to her old self.

Keep up with her reign of terror on "Grey's Anatomy," Thursdays at 9 p.m. ET on ABC.
