You're so right about the names!
I do think It may be only K and Fluffy that know lil A real name, they were the closest to Mr A and probably heard about it in passing.
That's what I was thinking too
I thought that was him cutting himself off from calling him brat again. K called him brat a bit before but stopped and called him little A I’m guessing to make him stop(little A saying he felt recognized as the manager cuz he finally called him little A instead of an insult)
Yea I could totally be reading into things to much #－.－)
Ok so I think some of the farm animals know little a's real name because in the beginning he said "my name is br-"..... because he got cut off then later in chp 10 after k finds out he's Mr a's nephew and he says "Bra- I mean little a.... " which was the start of little a's real name as mentioned in chp 1. also I think the pig is called Q because G mentions that he didn't want another mess like Q and in the beginning he was beating the crap out of the pig so it could be him
