John smiles slightly and says, "Harold..." Then he pauses for a moment, considering his voice of words, what he might say next. Harold Finch himself had said more times than John could count that he was a very private person and while John had learned plenty of things about him, there are certain things he knows he'll never tell anyone. They're Finch's secrets to tell, not his, and even if he's no longer here, John will respect that, too.

"I think he understood loss," he says. "And feeling as if something must be given up in order to save it. I also think he regretted many of the decisions he's made in his life, even if they were for a greater good. I think Harold, for all he was closed off from most of us, knew how important love could be to someone's life."

And he had taught John how to accept it. Not on his own, it's not a lesson he thinks he would have learned without Carter, but he's here now. In the end, he'd gone to Karen instead of a bar, and that means more than he knows how to say.
