"Sam asked you for help." It wasn't exactly a question, but a confirmation of that fact would be good. It would make it easier to make her point to Dean that it wasn't a good idea to fight with Zee and John for helping Sam when he'd asked them for help.
Dinah couldn't help a slight smile at the question. She shook her head just a bit.
"Dean is Sam's brother. Older brother," she said, as if that might convey a little more of how protective Dean was being right now. "I think it would do him some good to see for himself that Sam is still breathing. But I understand that if he did that, you would set the terms. I'd make sure that Dean understood that too."
