This morning when John Egbert woke up there was an aching pain in his neck, he shrugged it off and walked into the bathroom. He looked up into the skylight on the ceiling and hissed at it, the sunlight made his eyes feel like they were burning. John backed out of the bathroom and looked into the mirror above his dresser.
He was surprised to find that his eyes were an ice blue and the pupils are slits. They gave off a sort of glow, a little startled he adjusted to the change in his appearance. After he did he managed a smile, only to be greeted by a pair of long fangs. Blinking and rubbing his eyes he thought that it was only his imagination, but the glowing eyes and long fangs didn't disappear. I'm a vampire he thought to himself, not wanting to believe it.
Now it seemed that he can't go into the sunlight. So he'll have to carry an umbrella.
John looked through his wardrobe, everything he'd liked before seems too happy for his taste now. He takes one of his slime green ghost shirts and a plain black shirt that Karkat had given him, and then alchemizes it. He has created the 'Tear Vampire Slime Ghost'; he is pleased with the results and puts it on. Much better.
John suddenly feels a pain of hunger, but he was hungry for blood.
