Season 1
===“[[Pilot ]]”=== He was seen giving a suitcase to Raymond Reddington before he surrendered to the FBI. The suitcase contained all of Red's information and aliases, most of which the FBI had no knowledge of.
===“[[The Courier ]]”=== He tells Red that the package is in motion and that the Courier has been hired to complete the transaction. He reminds Red about an earlier incident in Cairo involving the the Courier.
After the rescue of Seth Nelson, he tells Red that he wasted his one question as it could have revealed their adversary or "could have made the world tremble". Red tells him he is betting on the long term.
===“[[Gina Zanetakos ]]”=== While Red is negotiating with a Middle Eastern client, he receives a call about Tom Keen being taken in for questioning. After his release Tom Keen states that Grey was the man who interviewed him for the teaching position.
===“[[The Good Samaritan ]]”=== Red tells him to make the arrangements for Luli Zeng's cremation. He is revealed to be the mole that helped Alan Fitch and Anslo Garrick raid the Post Office. Red kills him by suffocation, after spreading Luli's ashes, so the death will be ruled an accident and Grey's family will not know the truth.
