What character frightens pip on the way to miss havishams in chapter 28? At the end of chapter 28 what information does pip discover by reading the news paper?

Pip is frightened when he sees the one-eyed man he met in the tavern years before. This was the man who stirred his drink with the file (from Joe's forge) and gave Pip a one pound note.

From the text:

"I entertain a conviction, based upon large experience, that if in the days of my prosperity I had gone to the North Pole, I should have met somebody there, wandering Esquimaux or civilized man, who would have told me that Pumblechook was my earliest patron and the founder of my fortunes."
