The corpse bride. this is what happens when you are broken beyond belief. but you can make it back it is the hardest road. I've been through hell and back believe me it can be done. And after you've conquered that you will be unstoppable. I know I am. Thank you Lord for the Hardships. I am a soldier in training, a diamond in the making!
The actual line is Emily (the corpse bride) saying,"Pardon my enthusiasm." after her hand went running across the piano keys (this takes place after the piano duet), and then Victor answering,"I like your enthusiasm."
