I'm glad you've noticed. We met CJ at 15, he turned 23 in this story, and I've tried to show growth. The basic personality and instincts are still there, but he can now joke with Pam instead of snapping at her comments, and it's him running his hand down Owen's back trying to calm him. There's a purpose to everything I throw into a story, sometimes it's obvious, sometimes not. And sometimes it's crazy because I want to have fun.
CJ will still explode at times, but so do Brett and Cesar who are his idols. I think those two have done a good job raising their son.
