Now i personally think that kids are minor adults they replicate what they see and they do have their own character. actually i just think they kind of evil 1 is supposed to direct them abit.
But also whatever we are no matter how much we hide it, it eventually comes out. so a parent can give their child the best upbringing but they can still be bad.
but this Tia or whatever her name is, she is just evil and greedy. I wish they would give her character more characterisation coz it seems she is just naturally evil. I can so imagine when she grows up the actress playing Tai will play her and she would have to use mini's lol
