Chicken/Egg

The more I watch Mr. D and his friend George, the more I see of another of Mr. D's friends: Bobby.
The resemblances are amazing. The pauses. The switch of topics. The hand gestures. The stuttering The I'm-only-one-breath-away-from-the-other-side looks. And especially, the "I know something you don't shit eatin' grin".
Bobby and George could be brothers. Did Francis have another skeleton in the closet? LOL
Is "Bobby" George's alter ego or, is "George" Bobby's alter ego?
Is George the inner self or, is Bobby?
So, in a "nut" shell, who is the true self?
In other words: What came first, the chicken or the egg??
