Revenge
Hermione watched Harry pace around the tent worriedly. His face was thin and drawn, and he looked like death.
"Harry, why are you doing this to yourself?" She asked softly, fiddling with the blanket wrapped around her legs.
"Voldemort's getting stronger and stronger-"
"I know that." She told him flatly. "I meant this whole quest thing. You're seventeen! We're children! This shouldn't be our war to fight!"
"My parents died so he could be defeated." Harry shot her a glare, and his fists clenched.
"No, they died so you could live." Hermione corrected him, her eyes full of pity. "Do you really think they'd want you to die for a cause?"
"I need revenge, Hermione. I'm in too deep now."
"That's what I was afraid of."
