Jack Harkness feels the pain in love, in regret.
He feels the pain in sorrow and heartbreak.
He feels the joy and remorse, the scorching of the sun and the darkness of the night.
He feels the sadness running through the world.
He feels time in a small pocket watch.
He feels it all.
And he hears the words of defeat.
He sees the emptiness of the dead men's eyes.
He hears the final sigh and sees the body fall.
The words he hears must be from hell.
Because they burn and torture him.
They force him to face himself and carry all his weaknesses with him.
They shake his soul and he has to fight every second to keep going.
The words:
"Everything's going to end. You can't stop it. The human race is going to die. Freak."
