"It should," Childermass agrees and immediately turns to walk off towards the tree. "It's not any more complicated than cutting him down from the tree before he really does die."

Which will complicate things a little, seeing how Childermass remembers how this actually went very differently. To him, it only makes sense Vinculus was never dead to begin with. How else would he have suddenly sat up, alive and well, if he hadn't simply been mistaken? Only the thing is, when they do reach the tree, there is absolutely no doubt that this man here is extremely dead, a rope made from the woven branches of the tree itself the root cause.
