Hermione Granger: Harry, are you sure?
Harry Potter: I saw it! It's just like with Mr. Weasley! It's the same door I've been dreaming about for months, only I couldn't remember where I'd seen it before! Sirius said Voldemort was after something, something he didn't have last time, and it's in the department of Mysteries!
Hermione Granger: Harry, please just listen! What if Voldemort meant for you to see this? What if he's only hurting Sirius because he's trying to get to you?
Harry Potter: What if he is? I'm supposed to just let him die? Hermione, he's the only family I've got left!
