References

Season 1

• The Nigerian Job: The first reference to Star Trek occurs when Eliot Spencer, while flirting with a secretary at Bering Aviation, suggests that he plays a Klingon, the traditional enemy, at Star Trek conventions. Eliot then uses a Klingon phrase, further impressing the secretary, though (apparently) delivering it so poorly that Hardison (who was listening in) was put off by it.

Season 2

• The Order 23 Job: Alec Hardison both suggests and uses Star Trek code phrases to communicate with Eliot, specifically the dichotomy between odd and even numbered movies.
• The Two Live Crew Job: During a briefing, Hardison tells the team that the CIA calls Chaos the "Kobayashi Maru", which only Parker understands. The Kobyashi Maru is a Starfleet Academic test, presenting cadets with a scenario in which they can either save their own ship or attempt to save a civilian ship called the Kobayashi Maru (and end up failing no matter what). The expression has become a metaphor for an unsolvable puzzle, or "No Win Scenario", among those knowledgeable about the Star Trek universe.
• The Three Strikes Job: Hardison's final words to Lucille before the team blows her up were, "I have always been, and forever shall be, your friend. I'll never forget you." These words echo a dying Spock's final words to Kirk in the film Star Trek II: The Wrath of Khan.

Season 3

• The Ho Ho Ho Job: Nate draws a parallel between the EMP gun and Star Trek phasers.

Season 4

• The Cross My Heart Job: Elliot signals Hardison over an open P.A. system by paging "Kirk Picard," a reference to Captain James Kirk (original series) and Captain Jean-Luc Picard (ST: TNG).
• The Last Dam Job: Chaos expresses his desire to see Sophie dressed up as Counselor Troi, a character from ST: TNG. In the real world, the actor portraying Chaos, Wil Wheaton, also starred in the series as Wesley Crusher.

Season 5

• The First Contact Job: Elliot calles himself Willie Riker, who was the first officer on ST: TNG

Leverage: Redemption Season 1

• The Bucket Job: Parker suggests that Eliot and Robert Blanche (played by Levar Burton) spend some time watching TNG with her. Blanche responds with "What's TNG?"
