12 Grey's Anatomy Episodes Where Sandra Oh Shone as Cristina Yang

The first-ever episode of Grey's Anatomy really set the tone for Meredith and Cristina's iconic friendship. The two of them team up to solve Derek's Katie Bryce case with initial reservations about one another. Although Cristina has suspicions about Derek favoring Meredith because of their one night stand, the dark and twisty friends eventually make up and call a truce — in the least corny way possible, of course, because they're not about soppy apologies.
