Three clips from Thursday's all-new Grey's Anatomy shed light on the new interns' mindset.

Meredith and Cristina observe that they were once like these youngsters, and it's true. They talk a good game, but only to mask their various insecurities, and their competitiveness sometimes trumps their solidarity.

April Kepner may be a "dud," but she can still put an intern in his place like nobody's business. Don't underestimate her poise as a doctor, no matter how many reasons she gives you to doubt her mental toughness.

Meanwhile, Camilla Luddington's Jo decides to run with Alex's teasing of her instead of fighting it in a scene that shows there's definitely a spark between these two, whether she chooses to embrace it or not.
