The Doctor receives information that Voyager has suffered a massive Kazon attack and that most of the crew has abandoned ship, so he ventures from Sickbay, via remote holo-projection system, to aid those still on board. Once he's on the ship's near-deserted bridge, The Doctor must determine what is and what is not reality. Much to his confusion and counter to his program, The Doctor shows human life signs when, during a struggle with a Kazon warrior, he experiences injury and pain. He meets Lieutenant Barclay, learns of Dr. Lewis Zimmerman, the holo-engineer who wrote his medical holographic program and amazingly, discovers that The Doctor has a wife — Kes. He's in a state of disbelief when Barclay tells him he must destroy Voyager.
