The chapter, not anything on my part

there are 3 interesting quotes in the forsaken meeting in this chapter

Demandred: "al'thor has been seen in five cities, including that cursed place in the waste...since those blind fool-those idiots-failed in cairhien"

Aran'gar: "you were responsible for watching him [rand] osan'gar"..."you and demandred"

Osan'gar: "if you had ever read anything besides a history book you would know they're [the access keys] almost impossible to destroy!"

what was rand doing in waste? he wasn't going for the CK, because he already had them stashed in his room in the sun palace. was he going back for *angreal that may have been left behind? (btw where are all those *angreal that were on carts from rhuidean?) is he just trying to be elusive?

could this be a clue to one of demandred's locations? given his knowledge on rand's whereabouts might he be somewhere in the waste?

if the access keys are so difficult to destroy what happened to that one in the museum in the panarch's palace? the female one nynaeve melted because it took in too much saidar, when was that access key used to channel so much saidar before?
