What are pips feelings towards joe in the book Great Expectations from chapters 15-27?

Pip's feelings about Magwitch/Provis change dramatically throughout the book, mirroring his personal growth. He begins by being terrified by the prisoner Magwitch, then grateful that Magwitch doesn't name him as the food thief. On Magwitch's return from the Antipodes, when he's using the alias of Provis, Pip is embarrassed and alarmed at his presence, and appalled, confused, and even angry at the discovery that Magwitch/Provis is his benefactor. With time, however, and continued contact with Magwitch, Pip comes to see what sacrifices were made for his benefit, how dearly Magwitch loves him, and that Magwitch's only concern is that Pip be a gentleman. By the end of the book, Pip risks his own life to help Magwitch escape, and mourns sincerely as they wait in prison for the fever to overtake Magwitch.
