Ep 2. DNA

Red Dwarf season 4 episode 2, titled DNA, is an episode of the popular British science-fiction sitcom series that aired in 1991. The episode follows the crew of the eponymous spaceship, the Red Dwarf, as they encounter a rogue DNA molecule that threatens to alter their genetic makeup forever.

The episode begins with a bored Lister trying to pass the time by conducting a game of poker with his fellow crew members, Rimmer, Kryten, and the Cat. However, things take an unexpected turn when a rogue DNA molecule enters the ship through a breach in the hull.

Initially dismissed as harmless, the DNA molecule soon begins to wreak havoc on the ship's systems, causing bizarre mutations in the crew members that threaten their very existence. Rimmer's hologramatic projection starts to malfunction, turning him into various historical figures including a Roman emperor and a Viking warrior. The Cat's feline DNA becomes dominant, giving him the ability to see in the dark but leaving him unable to speak. Meanwhile, Kryten, the ship's android, grows increasingly paranoid as his programming begins to malfunction.

Only Lister, who lacks DNA due to being placed in stasis for three million years, is immune to the rogue molecule. Tasked with finding a solution, he teams up with Kryten to search for a potential cure, while Rimmer and the Cat try to adapt to their newfound abilities. Along the way, they encounter a rogue GELF (Genetically Engineered Life Form) who offers them a potential cure, but at a steep price.

As the crew races against time to find a solution, they must confront their own limitations and the implications of their altered DNA. The episode explores themes of identity, evolution, and the consequences of scientific meddling, all while delivering the laughs and dry British humor that fans of the series have come to love.

Overall, Red Dwarf season 4 episode 2, DNA, is a classic episode of the series that showcases the show's unique blend of science-fiction and comedy. With its witty writing, memorable characters, and quirky plot, it stands as a testament to the enduring appeal of the series, which has continued to attract a devoted fanbase for over three decades.
