So will someone explain why this is their favorite part?

as a kid grayson was also punished like that by ashley, whenever grayson did something to chase or koi he was locked inside his room for days without food or water and he doesn't even know he was being abused as a child and thought it was just how his papa show his love to him

This is where we get to understand more how his brain works, his reasonings and the logic behind those. His past will also be brought up.
