Doesn’t he have a pond doesn’t he just clean it? I do believe they should show it to us that he does clean his clothes because that sounds really nasty and what does he do for going to the bathroom?
dude’s been in the tower for months and his white shirt and sneakers are still clean without a single stain after all that farming.
