After doing some research trying to find out about Jacob, I cam across an unlikely link. Linus from Peanuts. Ben's last name is Linus, but this about Linus:

Linus is the only one who believes in the Great Pumpkin. Though he occasionally convinces other characters the Great Pumpkin is real, they always lose faith, while Linus keeps his.

Replace the words slightly:

Ben is the only one who believes in Jacob. Though he occasionally convinces other characters Jacob is real, they always lose faith, while Ben keeps his.

Thoughts?
