After catching Vega in a lie, Cho declares that in order to work together, he needs to be able to trust her with his life. His statement is ironic and somewhat hypocritical, since as an indirect result of Cho's addiction to painkillers after getting injured at work, Rigsby nearly lost his life in season four's "Ruddy Cheeks (2012)".
Cho also outright lied for Rigsby in Bloodsport (2011) when Rigsby gave a false alibi for his father, and said that Cho could back him up. After initially refusing to lie, Cho ultimately backs up the false alibi and says he "was there".
