Projections, VOY 2
As if the consciousness of The Doctor weren’t enough of a “what if” philosophical bone to chew on, this episode drops us off in full on Philip K. Dick territory.
The Doctor “is activated” only to be told that he is really Dr. Zimmerman, the man who created the EMH program. Wheels within wheels within wheels (plus a little flashback to the pilot episode) leave us unsure of exactly who to trust. This is one of those awesome episodes when you are seeing it through the eyes of the character and don’t know what to believe (Maj. Kira waking up as a Cardassian, for example.) Lots of fun.
