Transition- The Fade

In the following scene of Grey's Anatomy, Grey is telling a story she recalled as a child. Throughout this entire scene there are several fade ins and fade outs to recall her memories through flashbacks. In the beginning a lit up candle fades into siren lights, and then her face appears as the lights fade out.

Throughout this clip, she continues telling the story from her childhood. However, the flashbacks are not of her as a child but of her memories she recalls with Derek. She's still telling the story of her childhood when she was on the carousel, even though the clips being shown are of her and Derek. This could be because she is explaining how memory is a funny thing in general, and the director is showing this connection by having these clips fade in and out of each other. Her story about the carousel is a representative of life, which is how this memory of her childhood is relative to her memories with Derek.
