Matthew has gone through many trials and tribulations that have indeed challenged his certainty. His leader, the Invincible and Foolish Kamina, who has dared him to fight for his own justice, live according to his own codes. Simon, who has shown that courage and strength can arise from the most unlikely of places. Raynor Joz, so like the heroes of myth. And Joshua, who passionate intellect has unsettled Matthew in many ways–

"Aff!" He says, clenching his fist. "The coming of the Crusader Clans in force shall surely purify Terra of all it's dross!"

Oh right. Peer pressure.
