another thing that bother me, an 11 year old having a loving family and uncles not telling any of them about his suspicion about snap and voldemort.
Maybe it is because it is one of your earlier AU fanfic, but you really stayed to close to canon instead of following what should be expected from your premises. It would not have changed the story, but the trusted adults should be a sounding board not some that appear and disappear just when absolutely needed.
