John had figured as much, but still he nods when Karen says she's never told anyone before. Shifting forward in his chair, he presses a kiss to her forehead, then sits back again, dropping his hand back down to cover hers. Since finding her that day on the street, he had known something was wrong, deeply so, but he hadn't wanted to press her on it.

Maybe he should have. Maybe if he'd asked, she wouldn't have had to face all this on her own.

"I'm sorry," he says. "That you had to go through all this. That you had to do it alone."

He's sorry he couldn't stop it all from happening, sorry he hadn't been able to prevent the screening, although he knows, logically, it wouldn't have really made a difference. There are plenty of things John can do, crimes he can prevent, but Darrow is something else, something far bigger than what he and Finch had taken on together.
