Okay so theory: that incident had to do with uncle perhaps having wars and little A found out but everyone tried to convince he's delulu, G is apart of some bigger organization that will wanna take the farm or some shi. And uncle never did nothing against G bcs he's also a hybrid and Fluffy is some kind of a test subject for a de-hybridiziation medicine that works only partially and G took him from uncle and used it on him
I may be reading this as a form of therapy or just for fun....or to make myself suffer. :3
