Another thing reading fanfics has made me realize. Until you see how others headcanon things, you don't quite appreciate the horror of Sanji's childhood. Like, you watch/read it and get the shock value, and feel sorry for the character. But unless you spend hours analyzing it, or read fanfics depicting what-ifs, you don't fully grasp it. Like..
Stop to think, what would have happened if Reiju had refused to help? I see 1-4 things possibly happening.
1. Died (But he had food, so either eventually Judge would off him, his brothers, or himself).
2. Grew in intellgience and eventually sharpened a spoon, or tricked a guard somehow to escape.
3. Was let out for some who knows reason, least likely one to happen.
Or 4. The one we don't want to think of, a full grown adult still in a cell, having gone complete batshit insane from the solitude.( The say no man is an island after all..) Like those IRL horror stories of families locking up their kids and when they're rescued they're 'feral children.'
