Gabrielle stared at the notice in horror, shaken by its menacing face. When she last saw Dennis Creevey, he was scared, alone, friendless... was this why? Was this why he had nobody? He wouldn't kill anyone, she was so sure, not on purpose. She had feared for her own life, but he was in a state of desperation and let go. She was alive.
Perhaps being a vampire was difficult to manage, perhaps accidental crimes were part of the whirlwind of anxiety he seemed to be in last they met. The strength he had locked her in place with was definitely capable of destroying human beings but... he COULDN'T HAVE!
"Den-ees!" Gabrielle yelled into the air around her, wishing for answers, her notebook, despite the early morning's daylight. "DEN-EES!!!" She grabbed at her own hair, pulling it in desperation, not knowing what to do with her hands or any part of herself. Warm tears formed in her eyes, and after a moment of frantic glancing about, she stomped her foot like a child.
Jander would help Dennis. Or she would. Somebody. She refused to believe that the kind soul she met in Honeydukes had completely fallen to something so cruel. She never wanted to see Dennis again, he terrified her so, he put her in peril... but he deserved peace, and if Aurors caught him, it was over. If he had killed anybody, he was surely in despair over it, and she could not stand the thought of anybody enduring such a state... even the dead ones.
Someone with the right idea had to get to Dennis first.
