James peered at Severus for a moment before he got that little excited puppy look on his face and he was overcome with the intense desire to squeal like a small child and hug him. He felt very uncomfortable with this sudden realization. In fact, he had to scold his mind for that. Severus would not take kindly to him sporadically hugging him for just being adorable like a small child. In fact, he would not like being thought of as an adorably small child. Not that he was aware of, anyway.
His attention was distracted as he looked over at Al's words. "Someone's gotten into the cobbler already," he remarked with a smile. He'd have done the same thing...only he'd get in trouble because he was the "adult" here. Stupid being an adult.
"I see Al was quite correct in his representation of your smile," he noted. Oh, wait. Al might not have explained that. Lily knew, sort of. "Errr..." He'd let someone else explain that if they wanted to.
