...Regarding the Doll family.
First off, there's this guy. He's recycled from Eliot's old design from two years ago.
His name is Wyatt H. Doll
, and is now playing the role as Eliot's older brother. But that's not the big part. Instead of Eliot, he's going to be Angel and Elton's father
. Why? It's just that Eliot's been changed too much over the years, he's no longer suited for the role. Wyatt is more stern and demanding, which would result in a harsher childhood for Angel and his brother. (But not abusive, mind you.)
Eliot gets to be the weird, but loving uncle - as he now doesn't have children of his own. Wyatt gets the wife to lose while Eliot spends for most of his life is alone, at least until the business with Lecter and then Victor - which also means he would have been scoring for the same team always. Something that would have stirred up some family problems, including resulting daddy issues.
So, Eliot's life gets less shitty, and instead of the negative relationship with Angel that has always
been between them, they now have positive bonds. If Angel would have some sort of... weird attachment to someone despite his psychological condition, it would be to Eliot. It would be because Wyatt might have disowned Angel somewhat, after his diagnosis. So Angel turned to Eliot for positive vibes.
Another interesting thing that's changed, is that different from what's always been is that Elton gets to live.
His story no longer ends by being killed by Angel - but why Angel faces a serious jail sentence will be a secret until further notice. Now it actually makes more sense for Eliot to help him in his situation due to their positive relationship, giving him an even better reason to turn to John Lecter for help, as Wyatt no longer would want anything to do with Angel.
Redford, (Eliot and Wyatt's father) doesn't have a significant role until after he gets involved in the-MadDog
's story. Until then he works with confidential things in the Pentagon and by his own preference, stays out of the family situation.
