Tread Perilously attempts to tread safely with the Star Trek: Enterprise episode "Similitude."

It goes poorly.

When Trip is gravely injured after a Warp 5 experiment, Dr. Phlox devises a way to clone him and harvest parts of the clone's brain to heal Trip. But in order to do it, the clone must live four or five days growing to Trip's approximate age. When he begins to remember Trip's childhood, Archer is faced with with a classic Star Trek moral dilemma. T'Pol, meanwhile, is faced with unwanted advances from the Trip clone. Mayweather pilots a shuttlepod.

Erik and Justin determine Trip was the most popular Enterprise character and, by season three, the star of the show. Erik suggest an ugly tension between Scott Bakula and Jolene Blalock. Both credit the series with a great credit sequence despite its ruinous theme song. A prominent shot of T'Pol's ass leads to a discussion of fan service on Star Trek. Erik invokes Frank Miller's feature film debut, Will Eisner's The Spirit. Justin pitches a better version of the episode, but Erik suggests its similarities to The Next Generation's "Inner Light" boxed the writers in. He also determines that T'Pol is the star of the Vulcan Love Slave holosuite program.
