He's shaking uncontrollably. He wonders if there is any reason to live now.
Dumbledore is huddled quietly in the corner. He looks deep in thought, almost appearing as if Severus no longer exists. Severus doesn't care anymore - he doesn't care about anything but her.
Now, more than ever, the desire of her touch was overpowering. It was to feel her body pressed up against him. Yet, wanting that was idiotic, ridiculous; she had married someone else. She had had a baby who looked exactly like the father.
When he first heard of the murder, Severus once again forgot to breathe. He forgot to feel. He was waiting for the scream, the shouts, and the sweat…and to awake from the horrible nightmare. He started to laugh and laugh, because of how ironic the world was. Somewhat later, the tears came. There was a mixture of sickening laughter, and depressing sobs.
'I hate this.' He finally says to Dumbledore, but the headmaster does not respond. Severus throws something to the man and shouts, 'I HATE THIS!'
Dumbledore looks up because of Severus' outburst, and raises his eyebrows, 'What is it that you hate?'
'YOU WERE SUPPOSED TO PROTECT HER!' Severus shouts at the old man. Dumbeldore looks unnerved. 'YOU WERE SUPPOSED TO PROTECT HER! YOU WERE SUPPOSED TO MAKE SURE THIS DIDN'T HAPPEN!'
Severus begins to sob again, and Dumbledore lets him be; losing someone is worse than any sort of death.
