Rory's whole body shivered with such force that he actually rolled back in his chair a few centimeters - his way of recoiling from the question. He'd known that it was coming, of course, but that didn't mean he wanted to answer it. It was too much - he'd already said so many things that he'd been keeping bottled up for so long that he didn't even want to try to express this sentiment again. Not now. Especially not to another person who, despite caring about him deeply and having the best of intentions, just wouldn't understand. He could already guess what Eisen was going to say.
"I..." Rory ran a hand over his right leg. Generally, unless he was doing his exercises, Rory avoided touching the things, as their thinness depressed him, but at this point he needed a reminder, a tactile representation of why he'd done what he'd done. "You know why, Eisen," he said, his voice still soft. "I'm not... good for her. She deserves better than a man who can barely stand up."
