Dean certainly hadn't mentioned that the other vamp tried to kill Sam. Mostly because, when the vampire went around talking about how good the blood was, he didn't want a lot of specifics known about who he meant. Hopefully, the rest of his nest would just chalk it up to his extreme starvation making him think the blood was so different and incredible. Still, he noticed the strain in Sam's expression and looked over apologetically. It had crossed his mind to stake the fucker for attacking Sam, but he didn't want to bring the wrath of a whole group of vampires down on them.

"I think so. I hope so. As long as I remember to present myself appropriately when we enter new territories."
