i think the best way to describe the epilogues is as "incandescent rage at the last 10 minutes of the harry potter movies where the adults are all married and cops and have kids that they're sending back to hogwarts for some reason." it's adult in content but it was also written for like... "the type of adult that read homestuck as a teen," so waiting a few years is probably a good idea all around. but also wait until you're 18 because it's 18+.
