Harry Potter and the Half-Blood Prince
How we cite our quotes:
"In spite of all the temptation you have endured, all the suffering, you remain pure of heart, just as pure as you were at the age of eleven, when you stared into a mirror that reflected your heart's desire, and it showed you only the way to thwart Lord Voldemort, and not immortality or riches. Harry, have you any idea how few wizards could have seen what you saw in that mirror? Voldemort should have known then what he was dealing with, but he did not!" (23.154)
This is a moment in which we are reminded of why Harry Potter is the coolest and most famous little wizard known to man – he is true to himself, he doesn't pretend to be anybody he's not, and he goes through life trying to be the best wizard he can. Perhaps this is what Dumbledore means by "pure of heart" – Harry is unusually mature and soulful. Despite being an orphan like Voldemort, he hasn't grown cold as a result of circumstances or as a result of the way the Dursleys have treated him. He makes lemonade and battles on.
"And without thinking, without planning it, without worrying about the fact that fifty people were watching, Harry kissed her." (24.133)
Not only is Harry brave in war, but he's brave in love. Check this scene out. It's funny to compare Harry's journey to secure the first Horcrux with this journey to kiss Ginny, but both are admirable and both take great courage. Love is scary sometimes! But not for Harry the Brave. There's something private about this moment too – how is that possible?
"Dumbledore would have been happier than anybody to think that there was a little more love in the world," said Professor McGonagall curtly. (29.68)
Remus Lupin doesn't think he's a good fit for Tonks, considering his werewolf side. And, what's more, talking about their love for one another seems irreverent so soon after Dumbledore's death. McGonagall, who's typically very straight edged, gives her good advice in this moment following Dumbledore's death, encouraging the two lovers to express their feelings for one another, reminding everyone of how important love was to Dumbledore. There's a comfort in knowing that, even in spite of this huge sadness, people will carry on with their lives and will make the world better with their kindness and affection.
