A few of them talk third person. Jovi's very young, so Former Absolkid thinks that's why she talks like that. Former Absolkid thinks Chobin is weird. But Former Absolkid thinks that one of them may have learnt third person from the other. Former Absolkid thinks Jovi speaking third person suits her.
It's probably to make the game a little more humorous. Both are meant to be funny characters (well, maybe not Jovi as much) and don't seem very...clever.
It's only been made obvious a few times why Jovi talks in 3rd person, but I think Chobin simply doesn't have a good grasp of the language. I like the idea that Nomytaker brought up, though. (Been experimented on too many times)
cant you people see, there BOTH idiots, Chobins glasses are probabally affecting his brain and Jovi has probabally absorbed some of his wierdness, a 4ft man that is CONVINCED that you are a burgular at least TWICE must be playing without a full deck of cards
