“But I was willing to embrace mortal life again, before chasing immortality.”

“It is not about striving for immortality, but about accepting mortality.”

“To the Dark Lord,I know I will be dead long before you read this but I want you to know that it was I who discovered your secret. I have stolen the real Horcrux and intend to destroy it as soon as I can. I face death in the hope that when you meet your match, you will be mortal once more.R.A.B”

“And while I'm sure they're very admirable and brave and all the rest of it, I don't personally fancy the mortality rate -”

“We all know that the people we love are mortal, we all know we’re mortal, we know it’s going to end; you cannot prepare yourself for it.”

“Facing this stuff, in real life is not like school, in school, if you make a mistake you can just try again tomorrow, but out there...when your a second away from being murdered or watching a friend die right before your eyes...you don't know what that's like.”

“this is the comfort of friends, that though they may be said to die, yet their friendship and society are, in the best sense, ever present, because immortal”
