Unlike the others, Jamie hasn't made his way to the front of the group. He's further back, ostensibly watching over the horses of those who dismounted further back. However, that's not the real reason he's back there. Not entirely, anyway. While he is keeping an eye on the horses to a certain extent, he's also keeping an eye on the situation itself. Too many people have slipped away for his liking, and while talking seems to be working for now, he's not convinced it'll stay that way. Better that someone stay back and keep an eye out in case something goes wrong.

And if not? If nothing else, maybe he'll be able to get a better idea of what's really going on here. So while the others ask questions, he keeps quiet, not saying anything even though he's just as interested in the answers. Sometimes a little observation can go a long way.
