Fool Me Once - S2-E4

Trivia: Firefly reference. In that show, two agents were sent to capture the character River Tam. The agents wore blue surgical gloves and were foreshadowed by River prophetically muttering "two by two, hands of blue." In this Castle episode, after putting on blue gloves ("hands of blue") , Castle holds up two fingers on each hand one after the other ("two by two") then opens his hands.
