Well, he's had his secret in this show, but that was season three. Season six was supposedly all about secrets, and that every team member had secrets from the others. So far we have Garcia's lame "secret" that she acts in her free time (lazy writing much?), Reid's "secret" about having migraines, JJ's "secret" that the State Department or whoever was trying (and succeeding) to poach her. Prentiss' secret obviously is Interpol & Ian Doyle. But we haven't seen Morgan's (unless that was Ellie? Maybe?), Hotch's, or Rossi's. :/
