"Welcome to bein' human. Hope you survive the experience."
Well this was the brother of Sam. John dismissed Cas as unimportant and focused on Dean. "No. An I'm sure you're not used to hearin' that but might as well get used to it." He was staying firmly in the entrance so they'd have to bowl him over to come inside. They'd regret it if they did since Zee was on high alert with what she was doing.
"We're in the middle of tryin' to get him through this with his brain in more or less one piece. An I don't know you or trust you. One person can come in an talk to Zee about if you can come in an see him an that's the bird there." He pointed at Dinah and when he did they could see the blood that was slowly dripping off his fingers from the cut on his palm. It wouldn't heal until the spell was done. "Because even though she hates me I know she'll follow instructions an not touch anything or anyone unless we say it's all right."
