The truth was that his reaction and his disposition had attracted even Eric's attention. This was the kind of guy that would sell anyone at any point for any kind of profit.
Just the countenance he had while speaking all this time, and the way he easily told him everything he knew was enough to prove this point.
Eric would most certainly detest having such a person by his side, as he would never have any secret as long as he knew about it.
Most probably he would even die without understanding how it happened, so he had to be extremely careful around him.
But he didn't need every one of his followers or employees to work by his side. For example, this guy could work for his 'dear brother' or his dear 'father-in-law'.
Even though he might not help Eric much, at least would impede their advances. In that environment where every side wanted information about the other, he would be like a fish in the sea.
