Harry Potter and the Half-Blood Prince (novel)/Heartwarming

"Scrimgeour: I see you are - Harry: Dumbledore's man through and through. That's right."
 * "I'm not afraid. I'm with you."
 * Harry gets Dumbledore back in Harry Potter and the Half-Blood Prince. He notes how Rufus Scrimgeour accused Harry of being "Dumbledore's man through and through." Dumbledore notes, amused, how very rude that was of him. Harry then says he effectively accepted it as a compliment... and suddenly notices how very damp Dumbledore's eyes seem.
 * What perhaps makes this moment even better is this exchange right at then end when Harry and Scrimgeour meet at :

"Fleur (to Mrs. Weasley):' And what do you mean by zat? What do you mean 'he was going to be married?' . . . You theenk Bill will not wish to marry me anymore? You theenk, because of these bites, he will not love me? . . . Because 'e will! It would take more zan a werewolf to stop Bill loving me! . . . You thought I would not weesh to marry him? Or per'aps, you hoped? What do I care how he looks? I am good-looking enough for both of us, I theenk! All these scars show is zat my husband is brave! And I shall do zat (she takes the medicine and starts treating Bill)."
 * In Half-Blood Prince, Harry asks Luna to accompany him to Slughorn's Christmas party, and Luna is thrilled. The scene is sad, funny, and heartwarming; it's very well done. And despite the various sideplots also being developed at the party, we still get to see Luna thoroughly enjoy herself.
 * Throughout Half-Blood Prince, Molly Weasley, convinced that Fleur Delacour was a vain, shallow, and snobby girl, was dead-set against Fleur and Bill's wedding. At the end of the book, Bill . Molly is devastated, upset that "he was going to be married." Fleur asks Molly what she meant by "was", and yells that she doesn't care if Bill looks different, all that it will prove is that her husband is brave. The scene ends with Molly offering Fleur her great-Aunt's tiara to wear in the wedding; Fleur thanks her coolly, and then the two collapse into a hug and cry hysterically.

""It was a very lucky day for the Weasley family when Ron decided to sit in your compartment in The Hogwarts Express that day.""
 * Even the way Fleur's objections are ordered show her love for Bill: her first thought is that Molly is implying that Bill won't want to get married if he's disfigured, which might be a hidden fear of Fleur's. It takes her a few seconds to realise that Molly might be suggesting she won't want him any more - even though most of the people present think Fleur is shallow, the idea that his wounds would put her off doesn't seem to have crossed her mind up to that point.
 * The teachers all deciding, at the end of Half-Blood Prince, that Hogwarts must remain open.
 * The scene where, after Fleur says she loves Bill despite being scarred, Tonks
 * "It is high time your grandmother appreciated the grandson she has, rather than the one she thinks she ought to have."—Minerva McGonagall to Neville Longbottom. Professor, you rock.
 * In Half-Blood Prince, after Harry saves Ron from being poisoned and the Weasleys are huddled around his (Ron's) sickbed, Mrs. Weasley remembers every time Harry has saved one of them and we get this golden line from Mr. Weasley:
