(S03E06) Grey's Anatomy has a bad habit of hitting you over the head with parallels and symbolism. That's been especially true this season; it seems like every patient who comes into Seattle Grace teaches one of the doctors there a lesson about what's going on in his or her own life. In one way, these heavy-handed plot devices help take the viewer's mind off silly things like looking for subtle signals and just helps him concentrate on all the fun and games going on between the staff. But, it can also telescope what's about to happen plot-wise, making for very little surprise when said plot point actually occurs. In other words, Grey's ain't Lost, and it seems to be fine with that.
