She also urges him to pick a Chief Resident.
Lucy stops Meredith in the corridor and asks her what she's missing where Karev is concerned. Meredith tells her everything he's had to deal with, saying he puts on a tough guy act.

Spoiler for next week:
Callie's life hangs in the balance after the car wreck.
I love Karev and Lucy together! I was moved and saddened by Adele being diagnosed with Alzheimer's, and by the shocking proposal/car wreck with Callie and Arizona. Eli is too cocky! Jackson and Lexie continue to be hot together, I look forward to seeing how Mark will deal with this new relationship. April and Stark are an odd duo, but I somehow would like to see it work. Teddy was right - I don't feel it between her and Henry either. What a twist for Owen and Christina with him having to pick the Chief Resident! Great episode - can't wait until next week.
