Izzie walks down the hall and suddenly stops, and the camera pans around to show that Denny is standing next to her. He says her name, and she closes her eyes, seemingly hearing him. After a moment, she continues walking. After a sad moment, so does Denny, into the light.
Yeah, it was clunky and a little bit weird. But the relationships and the acting were all out of the park. I love Meredith and Cristina. I loved that Meredith got to say goodbye to her mom, in the only way she really could. I love that George is standing up for himself and his wife. Everything. No matter what the strange story, I really loved this episode.
