Sam considers the question with the weight it deserves. It's clear the other man has been around magic too, so he's not going to have to sugar coat anything. "It seems like a simple locking spell that uses blood as a base...that's not a typical use of magic where I'm from but it isn't unknown. I don't think it will take much to unlock the door...but that note wasn't clear as to how much we need to give up."

He frowns. It's like this place is playing games with its residents already and he doesn't like it one bit. If he hadn't watched Chuck being destroyed he'd say it was him pulling the strings here. "Someone is trying to put us at each other's throats and I don't like people who play games with people's lives." He'd lost enough and he wasn't about to just walk over someone else because he wants to get out of here.
