Time-Turner taught you anything, Harry? The consequences of our actions are always so complicated, so diverse, that predicting the future is a very difficult business indeed.... Professor Trelawney, bless her, is living proof of that.... You did a very noble thing, in saving Pettigrew's life." 

Amelia huffed.

"But if he helps Voldemort back to power 

"Pettigrew owes his life to you. You have sent Voldemort a deputy who is in your debt.... When one wizard saves another wizard's life, it creates a certain bond between them... and I'm much mistaken if Voldemort wants his servant in the debt of Harry Potter."

 "I don't want a connection with Pettigrew!" said Harry. "He betrayed my parents!" 

"This is magic at its deepest, its most impenetrable, Harry. But trust me... the time may come when you will be very glad you saved Pettigrew's life."

 Harry couldn't imagine when that would be. Dumbledore looked as though he knew what Harry was thinking. 

"I knew your father very well, both at Hogwarts and later, Harry," he said gently. "He would have saved Pettigrew too, I am sure of it."

 Harry looked up at him. Dumbledore wouldn't laugh -- he could tell Dumbledore...

 "I thought it was my dad  and hum who'd conjured our Patronus's. I mean, when I saw myself and Amelia across the lake ... I thought I was seeing them" "An easy mistake to make," said Dumbledore softly. "I expect you'll tire of hearing it, but you do look extraordinarily like James. Except for the eyes... you have your mother's eyes. 

Harry shook his head. "It was stupid, thinking it was him," he muttered. "I mean, I knew thye were dead."
