Okay, so they'd met at Colombia. There's been a girl with wild dark hair he'd dated for a few weeks, the one who liked hooking up in his car and only in his car, had that been Carla? There'd been a girl who'd he'd met in the law library, and then, several times, in the law library stairwell. She had the same kind of eyes as Rosario, he was pretty sure.
Or maybe, just like Rosario, they'd met at a party. That would be a funny echo of fate, wouldn't it? "Sure did, class of '99. Why?" he asked, and tilted his head a little, watching her curiously to see exactly how she was going to reply, from the widening or narrowing of her eyes to the changing of muscles around her mouth to the flare or not-flare of nostrils, he wasn't going to miss a thing. He aimed the question and fired: "Did you know him, back them?"
