Storyline

After John Sheppard is drawn to and touches a crystalline substance on a planet he and his team are exploring, several members of the expedition begin to have nightmares. Teyla dreams that Sheppard turns into a Wraith and feeds on her; and Dr. Jennifer Keller dreams she is called to sick bay to treat Teyla who is in excruciating pain while Sheppard looks on, apparently enjoying her suffering. Sheppard himself is fine but when the nightmares begin to spread to other members of the crew and one dies as a result of what happens in her dream, finding a solution takes on an even greater sense of urgency.

Remember Wolf in the Fold?
27 August 2014 | by (United States) – See all my reviews

Wolf in the Fold was an episode from the second season of Star Trek (original series), in which the crew had a murder investigation that resulted in the discovery of an entity that feeds on fear.

Doppelganger doesn't exactly parallel with the ST:TOS episode because no one's been murdered (though there is a fatality involved), but the similarities in plot theme are made clear as this episode unfolds.

There's another thinly veiled reference to a Sci-Fi classic in the opening scene, where McKay asks if the team has any idea of the number of stargates in the Ancients' database with no information about the planets they're found on.

Sheppard's response: "42." Douglas Adams would have been proud, because I laughed right away.

Then there's the reference to the Alien movie, where Dr. Keller has a dream about an alien "thing" bursts through Teyla's abdomen and the characters discuss the effects that film had on them.

This is kind of a spooky episode, so if you like a little spookiness with your Sci-Fi, you'll probably like it. I only gave it a 7 because McKay's annoyance factor is off the charts in Doppelganger.
