Is it just me, or does Grey’s Anatomy just get more addictive with every episode? My nominee for the week’s best moment had to be the interaction between Alex (Justin Chambers, left) and prickly Cristina (Sandra Oh). As if her matter-of-fact instruction in how to perform a breast exam wasn’t priceless enough, Alex’s reluctance to seek her help resulted in my favorite bit of dialogue: ”Okay, evil spawn, you can nurse your pride — the keyword being nurse — or you can pass your test and be a doctor. It’s up to you.” What was your favorite moment in last night’s episode?
