I'm here for that ending. The middle is good, but the way it comes together at the end is very good. It's a great leadup for the final line, and it retroactively justifies a lot of the imagery (obviously, that's the point). I think being sick is making me have trouble coming up with more words for this comment, but I will say that I spotted just a couple SPaG errors, which I would go back and fix if I remembered what they were (yet again, not fully here right now), so you could probably do a once-over, I remember specifically a sentence missing a word or something like that.
I'm always here for more thematic development around amnesticization and portraying the Foundation as "angelic," like, contrasting what they are doing with how they are viewing themselves (that's sorta the vibe I got, "we're helping you" while they spill the memory-water out of the bucket), it's neat. I approve. +1 obviously.
