Sam rose as soon as she did. He hated seeing her upset, but what could he do? The feelings weren't exactly mutual. He figured that she was better off finding someone who could appreciate her just the way that she was anyway. It was what she deserved, after all. He nodded at her comment on the ghosthunting bit, then offered her a small sort of smile.
"I should probably get going," he told her. "But I'll be around if you ever need to talk again." He turned away from her and started walking. He only paused momentarily to look back at her before setting off toward Dean's car.
