Caz is a friendly member of KK's O'Jacks team, appears to be more reliable than average. In Rusche's rundown of the O'Jacks employees in the author post below this comic, Caz is listed under the title "The Sarcasm" and stated to look for the humor in life. He was also the person who KK picked to train Ellie. Caz and Tommy have a game going where they try to guess what a drive-thru customer looks like based upon their order.
