You and Matthew hated each-other, both on and off the Criminal Minds set, he would berate you if you did anything wrong;

"Listen, you little brat: I'm smart, you're dumb. I'm big, you're little. I'm right, you're wrong and there's nothing you can do about it!"

Matthew said as he was stood in-front of you, berating you because you didn’t get one of your lines right on set and you didn’t act the way your character should’ve acted.

“Get out of my sight! I don’t want to see you again!”

He shouts at you and pushes you away after giving you a good tongue lashing.
