“The Death Eaters can't all be pure-blood, there aren't enough pure-blood wizards left," said Hermione stubbornly. "I expect most of them are half-bloods pretending to be pure. It's only Muggle-borns they hate, they'd be quite happy to let you and Ron join up"
"There is no way they'd let me be a Death Eater!" said Ron indignantly...."My whole family are blood traitors! That's as bad as Muggle-borns to Death Eaters!"
"And they'd love to have me," said Harry sarcastically. "We'd be best pals if they didn't keep trying to do me in.”

“I'm Draco Malfoy, I'm Draco, I'm on your side!"
Draco was on the upper landing, pleading with another masked Death Eater. Harry Stunned the Death Eater as they passed: Malfoy looked around, beaming, for his savior, and Ron punched him from under the cloak. Malfoy fell backward on top of the Death Eater, his mouth bleeding, utterly bemused.
"And that's the second time we've saved your life tonight, you two-faced bastard!" Ron yelled.”

“What's that?" he snarled, staring at the envelope Harry was still clutching in his hand. "If it's another form for me to sign, you've got another -"
"It's not," said Harry cheerfully. "It's a letter from my godfather."
"Godfather?" sputtered Uncle Vernon. "You haven't got a godfather!"
"Yes, I have," said Harry brightly. "He was my mum and dad's best friend. He's a convicted murderer, but he's broken out of wizard prison and he's on the run. He likes to keep in touch with me, though...keep up with my news...check if I'm happy....”
