So, tonight’s episode raises the interesting question.
How come Kate & Company can go over the wall, but Smokey cannot?
Speaking of which…have we ever even seen Smokey in his entirety more than a few feet off the ground? Maybe the ratchety sound that tried to drag Locke underground in season 1 is more than just sounds. Maybe it implies that there is some sort of system that ties Cerberus (smokey) to the underground like a leash. Like the fields that make the particles behave only work up to a certain height because they attenuate too much.
