AVClub: Any show churning out over 22 episodes a season is going to wind up with some filler. After the inventive storytelling of “The Sound Of Silence” and “Unbreak My Heart,” Grey’s has been spinning its wheels and waiting for another big event—which looks to be next week’s two-hour hospital lockdown episode. That’s far from the worst thing in the world. My general affection for these characters and this world carries me through even a so-so episode. But it’s hard not to notice that other than inching the April/Jackson story forward a tiny bit, “I Wear The Face” doesn’t really do much to advance the season’s larger arcs. And, unfortunately, there’s not much compelling episodic storytelling to make up for that either.
