Meredith: He's your dog now.
Meredith: I miss him. (Derek nods an is about to say something, Addison walks up and interrupts)
Addison: He misses you too. You should come visit. (Meredith looks uncomfortable. Addison chuckles) The dog, I mean.
Meredith: I'm walking away now. (leaves)
Addison: So um I'm looking for a neurosurgeon to consult on a fetal spinal tumor. You know anybody good? (Derek laughs)
