Greetings everyone, i finished the series a couple of days ago and there's a question that keeps bothering me:

Kaladin becomes a Herald and while his body and soul go with the other nine Heralds to the Damnation, his mind goes somewhere in the Spiritual Realm (sorry for eventual naming mistakes, i did not read the english version) to help the other heralds and prepare for the "Last Return".

My question is: how is the last return going to happen? Their minds are not on Braize, therefore they can't yield to torture; even if they did, the Fused are already on Roshar and can be reborn in Retribution's new storm, therefore what difference does it make (sure, with the new pact the spren are protected, but what about everything else)?
