Meredith: April, you should go. [April leaves] Lexie, I had a miscarriage that day. April was there. That's why she knows about my doctor's appointment. And I did know that Mark slept with Amy but I didn't think you cared. I can never tell what the hell's going on with you two. And as far as the psych ward goes, you are not alone; I sat by your bedside for 36 hours while you slept. You're not crazy, Lexie. You're a Grey.
