on the still hanging "Goodbye J.D." cloth, showing him marrying Elliot, having a child with her, sharing Christmas with Elliot, Turk, Carla, Dr. Cox, Jordan and all their children, his grown son Sam getting engaged to Turk's grown daughter, Isabella, and showing off to J.D. and Turk (and faints two times), him hugging everybody in those visions, and finally him getting an honest hug from Dr. Cox. This sequence is constructed in a musical montage style, and is accompanied by a Peter Gabriel cover of "The Book of Love", originally written by the Magnetic Fields. The cloth is torn down by an unfamiliar janitor (played by series creator Bill Lawrence) who says goodnight to him. With that, J.D. gets into his car and drives off. Production On his blog, writer Bill Lawrence admitted that the dialogue between J.D. and Elliot in bed at the beginning of the episode was lifted from the pilot of a previous show of his, Spin City. Also of note, the doctor who says "adios" to J.D. as he leaves the ICU in the final attempt for Dr. Cox to give JD a goodbye hug is Dr. Jonathan Doris, upon whom the show is loosely based. Cast It was reported a week after filming in September 2008 that the finale of season 8 would feature a large cast of characters who had appeared throughout the show's eight-season run. Over fifty actors reprised their roles as patients, medical staff, and supporting players from prior episodes for the finale. Heather Graham was also invited to reprise her role as Dr. Molly Clock, but declined for personal reasons. Masi Oka, who played Franklyn the lab technician, was then appearing on Heroes, while Sarah Lancaster, who played Lisa the Gift-Shop Girl, was then appearing on Chuck; both were asked to appear but were denied permission by NBC.
