I think PitBulllady about covered all the angles but I'd like to look more deeply at the first one.

One of the reasons humans have come so far is their ability to form complex social groups together (super-organisms) and it stands to reason the mechanics of this are biologically written in our brains like organic computer programmes. A young human brain needs to develop these programmes, explore their capabilities and find their boundarys. In the absence of other human brain to practise with, perhaps human minds make test models - not independent but not under conscious control neither. This is certainly within the brain's capabilitys given that Soviet scientists discovered that a single brain physically seperated creates two personalities and all kinds of physical and psycological conditions cause the generation of independent voices in the sufferers head. Is it possible that early interaction with one's imagination can actually prevent such conditions by accessing the internal levers that control personality?

You must forgive me. I love speculating on this stuff. On a lighter note, Bloo compensates for Mac's good hearted, modest and considerate nature as he is totally egocentric. He is Mac's confidence and drive and thus they always prevail together but never alone.
