We suspect it could be because Sara Ramirez (Callie Torres) worked her gorgeous butt off this week, promoting the episode (and the show as a whole) to tons of different media outlets — TVLine.com and The View, to name just a couple. It sounds like Sara’s hard work definitely paid off!
Another reason? Last week’s episode was, in our opinion, the best of the season — even the most diehard Grey’s fans can get bored of hearing about portal veins and intern stuff sometimes, and Episode 9 gave us everything we love about our favorite show: drama, Calzona scenes, and a really surprising ending that made us want more!
And, of course, the obvious reason: Grey’s Anatomy is just awesome.
