 Dr. Lewis Zimmerman comes to Deep Space Nine with the intent of using Dr. Bashir's physical and personality likeness as a template for a Long-term Medical Hologram (an LMH), as opposed to the short-term Emergency Medical Hologram installed on such ships as and the "Enterprise"-E. Whereas the EMH, which Zimmerman used himself as the model, is for short-term emergency use, the LMH will provide full time medical care on distant and isolated outposts where it might not be possible to station a doctor.In order to make the hologram as robust as possible, Zimmerman needs a complete personality profile on Bashir.In addition to questioning Bashir himself, Zimmerman interviews Bashir's colleagues and makes arrangements – against Bashir's wishes – to invite Julian's estranged parents, Amsha and Richard Bashir, to the station.
