What I mean is this, back then when Sawyer and Locke were time skipping they go to a well where the orchid was going to be built. After Locke goes down the well they skip in time. Sawyer, Daniel, Miles and Juliet end up in a time way before the well was even built. Since Sawyer was holding onto the rope Locke was on the rope goes back in time with him. The go way back in time when the well wasn't there, so now its just a rope in the Gounod. After that Sawyer lets go of the rope and they do the final shift to the 70's. The rope in the ground was left behind, which probably some one found and end up digging deep enough to find the donkey will. This started the whole magnetic anomaly. If the rope didn't exist now one would have found the wheel or the magnetic anomaly, which probably ended up sinking the island.
Anyone follow?
