Goldfish do not have a three-second memory; that is a complete myth. Scientific studies have proven they can retain memories for at least three to five months and can remember routines, recognize their owners, navigate mazes, and tell time.
It seems to me more like he's been told he's useless and stupid, with everyone constantly pushing that stereotype onto him, and with his trauma intensifying things, he ends up forgetful. But we can see he's not truly like that - he remembers facts about all the plants, clearly has repressed memories of his childhood, etc.
super skinny and hair unkempt but still looks freshly shaven
if you compare the previous chapter to this chapter, you can see his hair is super overgrown meaning its been atleast a couple weeks so in that time (no matter how slow facial hair growth(which isnt that slow)) ATLEAST a stubble has to be seen. and i think the muscles is odd but maybe its just brcause he is super skinny now and its just his bones and whatever organs showing(??)











20 chapters (21-41) worth of flashbacks… damn im so lucky i let it marinate until today because i wouldve dropped this with the amt of flashback there was.
