What did Yazoo say to Reno that made him so mad (SPOILERS)?

In FFVII: Advent Children, there was a scene where a bunch of goblins attacked the city. Yazoo and Loz (I think that's their names) stood in front of a monument with Reno and Rude coming towards them. Then Yazoo insulted Reno in some way. He said something like, "The ? can't be trusted," then Reno got all mad. Does anyone know what Yazoo called him?
