Hate
He had never hated someone before; sure he had despised and disliked…but never hated, this emotion, if you could call it that was new. He couldn't think or breathe or feel, so wrapped up in the emotion assaulting him.
She was being tortured.
She was being tortured by that vile bitch, she was screaming in an agony so heartbreaking and here he was floors below in this bloody hell hole, not able to do anything.
He banged the bars again, and again, and again and yelled and screamed and cried. 'That bitch deserves to die, that effing whore needs to die' was all he could think as he listened to Hermione scream.
Then the hate shifted, how could he have let this happen to her; let her have to go through this, once he got her back-without even telling her he loved he…how he has loved her for years.
Hate is a poisonous emotion affecting everything around it.
