CRISTINA'S STORY LINE
Cristina's been through hell on this show — actually, she's been through it about once a season. But now that she's settled down on the relationship front, her story arc of personal anguish in the wake of the shooting gets to take center stage. Sandra Oh's acting has always been one of the show's greatest assets, and she's getting some of the best material she's had in years.
CRISTINA AND MEREDITH'S FRIENDSHIP IS STRONGER THAN EVER
Romance, schmomance. The best relationship on this show is definitely Meredith and Cristina's, and this season it's been even more important. Both docs are dealing with some serious issues following the shooting — Meredith's miscarriage, Cristina performing emergency surgery — but they're helping each other cope. Who wouldn't feel better snuggling with Meredith and Derek?
