"Why the fuck did you do this?" The voice was a knife cutting into skin, sharp and deadly.
The voice that came out of Snape's mouth was lifeless; the effect that veriteserum had on people. "I needed to teach you that people cannot be trusted."
"So you fucked me."
"Yes."
His voice caught as he finally replied. "Fuck you."
Snape's voice held a sneer in it as he replied "You already did."
Looking as though he would start crying he steeled himself then spun round and left.
When Harry left Snape felt triumphant. No one could ever break Harry Potter.
