Theory Briefing

• A fan theory claims the Dursleys were kind people warped by Harry's Horcrux presence, but Harry would then have attracted cruelty from nearly everyone he met.
• The Friends theory that Chandler lied about his own fertility to protect Monica ignores the very next episode, where he actively searches for a sperm donor.
• Both theories ask fans to ignore direct on-screen evidence in favor of a more emotionally satisfying hidden explanation.
• The Reddit thread frames these as cases where a clever premise sounds compelling until the source material pushes back hard.
