btw guys, just wondering because its been bugging me. If Roland gets sent back to start his journey again(well, his journey from the desert) then what happens to the now recovering beams? do they go back to being destroyed again? surely Roland hasn't been sent back in time, because the keystone world is one way, so surely this would be impossible? But if he hasn't, and he comes across people such as the people of the Calla, or River Crossing, surely they would recognise him? Or has he been sent to another universe of some kind, to redo his journey there? its all confusing!( altho I like the fact that we're left with so many questions, it means I won't forget it in a hurry!
