Addison’s patient, Lily, has Stage 4 ovarian cancer and needs to be admitted to the hospital. But she’s not going anywhere until someone she trusts agrees to watch Milo, her cat. This just in: Addison Montgomery has just been cast as the new Catwoman!
Addison gets into caring for the cat. She even buys Milo a new travel carrier. While on the way to visit Lily, she runs into her cute oncologist, Dr. Brian Reynolds (guest star George Newbern). He asks her out and she accepts. The pleasant moment doesn’t last long as they reach Lily’s room to discover she’s passed away. Addison thinks she may end up like Lily, dying alone in a tiny room without friends. When Lily’s cousin shows up at Addison’s office, she offers to take Milo off her hands. That’s not going to happen.
