While I really enjoyed this episode I feel they missed out on the scale of the Aiel in the visions. There should have been huge camps of Aiel moving around - but it seemed that there was only a handful of people travelling with the Tree of Life. In the vision after the Tuatha'an left there seemed to only be the grandfather and grandson and noone else which was strange.
There should have been a huge number of Jenn Aiel which dwindled over time so the size of the camp should increase as they go back in time, not decrease.
