PRESTON: [pause] "Cristina and I are engaged."
PRESTON: "She doesnâ€™t want to tell anyone. At least, not until she tells Meredith first."
DEREK: "Theyâ€™re different than other women."
PRESTON: [Laughs] "Yes, these women. Yes they are."
DEREK: "You know, maybe weâ€™ll never know them. I mean really know them. Now that you and Cristina are engaged, youâ€™ve got a lot of work to do."
