He watched Renard's Confidant in Vienna while the confidant was speaking to Renard by phone. He later followed the confidant to Portland and placed a bomb to kill the confidant, Renard, and anyone else in the area. After Renard disposed of the bomb, he killed the businessman. Renard searched the man's body and found a French passport in the name of Henri Leseuer.
Renard briefed Nick and Hank about "Henri Leseuer" and told them that it was all a lie. He went on to explain that the man's real name was Augustine Katt and that he was born in Malta in 1973. Katt joined the French Foreign Legion at age 17 and did well. He disappeared in 1990 and resurfaced in 1998 with a new identity working for the Verrat.
