"…Goblin notions of ownership, payment, and repayment are not the same as human ones. […] We are talking about a different kind of being," said Bill. "Dealings between wizards and goblins have been fraught for centuries. […] To a goblin, the rightful and true master of any object is the maker, not the purchaser. All goblin-made objects are, in goblin eyes, rightfully theirs." (25.93)
Bill reminds Harry that not everyone can be held to the same human standards – goblins have their own identity as a species, and thus live by their own rules.

"Karkaroff intends to flee if the Mark burns."
Dumbledore's comment that Hogwarts Sorts its students too soon implies that Snape's bravery should perhaps have placed him in Gryffindor – his true identity, which nobody else knows about, shows him to be as courageous and loyal as any true Gryffindor.

"Tell me one last thing," said Harry. "Is this real? Or has this been happening inside my head?"
This is such a classic Dumbledore thing to say. It's a little trippy, a little goofy, and a little (OK, incredibly) deep and profound. Basically, he's telling Harry to trust what goes on inside his head – just because it's happening in there, doesn't mean it's imaginary or silly.
