There was no point in small talk, not really. It was good enough for a few minutes, while they were ordering, and Sam wouldn't have brought up anything so sensitive while a barista or other customers were nearby. But this was the second time they'd met up to talk about this, and he'd been willing to go right to talking about himself pretty quickly. Now, when it was important to figure out what was happening to her, he figured that dropping the niceties was allowed.
He listened, and nodded to indicate that he remembered what she'd told him before. He'd figured there was more to it, but hadn't pressed the subject at the time. And there was no real need to press it now either, when she was being forthcoming.
The idea of a Mantle that would consume her within ten years was... terrifying. He thought of the Mark, and the way it had taken over Dean so quickly-- and how he still had no idea what to do about it.
He also registered, vaguely, that she'd said Argentina. Which meant she had been with Mara, probably, but that suddenly seemed thoroughly unimportant in the face of everything else. "How did you get the Mantle?" he asked. "I mean... how is it transferred? I know you said it was forced on you."
And the harder question. "I'm going to guess that wasn't intended, either," he said, more quietly. "Can you tell me about what happened?" It was a hard subject to talk about, he could appreciate that. But he couldn't really form any opinions, much less possible solutions, without hearing more details.
