about Roland and the loop I can't make up my mind how should i think about it...
Spoiler:
Is Roland older with each "loop"? Or will the dark tower take him back in time? Will he get a new body every time? If he gets a new body then it's kinda maddening - he forgets everything also so it would be like a 100% new start with the small add from the dark tower. Or does he start the new turn with his old body? If so then arthritis would get him killed - and the lack of fingers i have a whole bunch of these questions maddening me and i can't find an explained answer to any of those
