In the first game, When George's head is hit by a wooden samon and loses conciousness, Nico shows up from the rooftop and manages to kick Flap and Guido to get the tripod. Even George is impressed after that.
How about in the second game where Nico saves George at the pyramid before he becomes Tezcatlipoca's sacrifice?
In the third game, after George receives the Psi stone the Preceptor says he'll send his best knight. The Preceptor calls one of the Templars to bring a long wooden case. George realizes that the Preceptor holds the sword and tells him to kneel. For a man who experiences a lot of adventures, George finally deserves being a knight.
