This snippet from Talk Of The Town shows Carl ready to reveal some of his feelings for Craig after a confrontation with Mike–
Carl reached out and put his hand on the back of Craig’s neck, pulling his face to his chest. He felt wrenching sobs entering him as he gently rested his chin on the top of his head, closing his eyes. If he would have gone into the kitchen and stopped Mike right there, like he was sorely tempted to have done, he wouldn’t have been able to control his demon. He would have ripped Mike apart on the spot. Any possibility of anything with Craig would have been gone, he could not have taken the chance on Craig seeing that. He refused to take him if he was not willing.
But at this moment? If Mike had been standing before him, Carl would have gladly bled him dry.
