I agree that the future she witnesses is suspect for the lack of presence of so many of the current-generation antagonists. I first read this thread before the scene itself, but even with an idea of what was to come I found it peculiar how NO ONE from the current characters was around ~20 years later except for a clan chief. However, that doesn't change the emotional impact (for myself) of Rand's last descendant being killed for stealing food from a garbage pile.

I also thought it very strange that there was a reference to Rand bowing and submitting to the Crystal Throne and Seanchan Empress since I'm pretty sure that's now how it's really supposed to be / going to happen.

I'm pretty sure we can agree that Aviendha will take this back to the other Wise Ones and Rand as a warning to deal with the Seanchan once and for all before the Last Battle, especially since he's not yet succeeded in making an accomodation with them per the Prophecies, Dreams, viewings, etc.
