how does pips realtionshipp with jaggers change when Pip comes of age?

Jaggers questions Pip as to the nature of his spending and debt, and appears triumphant when Pip is unable to qualify his spending. Pip finds Jaggers quite intimidating: indeed the encounter on his birthday

'reminded me of that old time when I was put on a tombstone.'

Jaggers resolutely refuses to tell Pip the identity of his benefactor and this leaves Pip 'intensely meloncholy.'
