Sam and Shosanna
Shosanna feigned shock at his words. "I don't know what kind of girl you think I am, Sam Winchester." She couldn't keep a straight face at this, though, because she had a feeling she knew exactly what kind of girl he thought she was. And it definitely wasn't a bad thing, either. She flashed him a small smile, "Maybe you can warm me up later, then. If I'm still a little chilly, that is." She gave him a wink as she spoke.
"And I am glad to have a friend like you," she told him, as she squeezed his hand lightly. She liked the feeling of his hand in hers, it felt... right. Shosanna was glad that he had decided holding hands was acceptable, because it was something she'd wanted to do.
And if he chose to tell her about his evening with Jack? She wouldn't hold it against him, not at all. After all, they weren't in a relationship. Yet. She couldn't really expect him to just sleep with her. Or tell her about anyone else he slept with.
