I have always declared myself to be a supporter of Sam, and would prefer him to get the £100,000 rather than Dexter and Gina [because he needs it the most]...[and still do!] but I am also aware that the lad has been totally taken in by his Svengali...the Creepster Callum!!...[in fact he is so far up his arse, that all I can see of Sam is his feet!] [
Sam type pun! 
]...So it only stands to reason that he would feel the need to share 'a common enemy' with his master! ...it's his understanding of loyalty.
