Sam has a fear of kids in BA and BL both, so he would be wary and staying as far back as he could. If Jacob was unconscious close by, he would try and revive him.
Dean’s really good with kids, even the larger ones, so he’d do his best to coax the kid. They need to get out of there, and the kid is the best one to do it. I have faith Dean will be able to get them to respond to him, and maybe go find Jacob.
