They fast-forward to present day ten years later, where he has been hospitalized and is on life support. The Marin County Civic Center stands in for the medical facility. Eminem raps next to him as he is floating in an isolation tank, during which the figure of the Pythia (played by Canadian actress Estella Warren) is singing as a hologram behind and over Dre, mouthing the words to Skylar Grey's vocal part in the song. Skylar Grey herself appears as one of the doctors in the video, but never actually appears singing her part.
