Allen McKendrick
Allen McKendrick comes from a long line of politicians. His
father was a congressman, his grandfather had been
governor.  He knew from an early age that he would not
only be a politician, but he would be president.

Even if he had a stepping stone to get around, Thomas
Quillon, who was slowly but surely wiping out children with
abilities.  Children like Allen, who comes from a different
generation from Sam.

He embraced his abilities as well as his political destiny, all
planned by the demon, even as he does good works and
genuinely helps people.

Sam came to him under the pretense of being an intern, but
that con quickly fell by the wayside as they  realized how
much they had in common.
He even proved helpful when Sam was
captured, and earned Sam's trust by not
turning his brother over to the authorities
that were still searching for him.  Well
aware of the deal the Winchesters had
been forced into with Quillon, and their
own unique experiences with the yellow
eyed demon and his rival, he still
stretched out his hand, offering to help.  
He gave the Winchesters refuge and
medical care.  

But he is a politician.  And he is one of the
special children who has accepted the
demon into his life.  He has his own
agenda yet to be revealed.  But
guaranteed the execution of the agenda
will not be neat, and it will not be pretty.  

The only real question is, has he
underestimated the Winchesters, as
others have done before?  And exactly
how much is he controlled by the demon,
if he even is at all?
