Kes falls in love on an away mission. The Doctor, seeking to expand his programming, incorporates the personalities of several historical figures. B'Elanna Torres chastises The Doctor, warning him that his program is complex and the results could be unfavorable, but it is too late, as the Doctor develops an alter-ego - a violent, unethical personality who attempts to murder Kes' new beau.

This episode gives us the first confirmation that holodeck characters are indeed hollow, possessing no internal structure. See more »


When the Doctor shows Kes the various characters with whom he interacts in the holodeck, "T'Pau" almost knocks over the kal-toh (Vulcan chess) structure by bumping it with the piece she is supposed to be placing delicately. See more »


The Doctor: I think I'm detecting a reaction to your recent break-up with Mr. Neelix. The Mahatma would recommend a cold bath. Simplistic, but no doubt effective.

User Reviews

While I usually love the Doctor, here he seems wasted and silly.
19 February 2015 | by MartinHaferSee all my reviews

I think that the Doctor (Robert Picardo) is the best member of Voyager's crew. He's funny, snippy and very interesting as his character evolves throughout the series. However, occasionally the show really struck out when it tried to expand his character and "Darkling" is clearly one of these times.

The Doctor is trying to expand his programming by interacting with various historical characters. Unfortunately, this has unforeseen effects on him and he becomes a 'Jekyl & Hyde' sort of personality. At the same time, Kes is considering leaving the ship and going on an adventure with a new guy she just met. How these two plots interact is something you'll have to see for yourself.

The problem with this one is that changes in the Doctor are just fine--insane and HUGE changes aren't. It all comes off as very contrived and silly. The only real positive I see in this show is that the writers finally decided to have Kes and Neelix break up-- which is so positive as Neelix's jealousy is so boorish and annoying....and a bit creepy.
