How long did John silver manipulate Jim Hawkins when they met at the spyglass?

I think Silver is manipulating Jim the whole time. In this chapter, you again see the best father figure of the book in action, Long John Silver. As Long John Silver makes special protection to take care of the younger Jim, it is like he is a father taking care of a son. The special bond between the two characters is reinforced by their taking care of each other at a time in both of their lives when they need someone else.
