So. This is some sort of strange idea I've not been able to remove from my head. I suppose we'll assume that Thalia's some sort of psychotic murderous vampire. A drabble, and this drabble is not really supposed to make sense tbh.
This is her favourite thing (this is her least favourite thing).
Really, she loves these blood baths. Only she can create them. Biting fiercely into necks - pale necks, tanned necks, bloody necks, clean necks, moist ones, dry ones, dead ones. She isn't crazy. Honestly. But she misses him so and it's all Percy and Annabeth's faults, frankly (it's really all Thalia's fault, though).
She only ever has fits of piercing necks with her elongated fangs and snapping necks when she sees them. She didn't want to kill them. She'd loved them, really, but something had come over her. She's a monster. When she thinks about it, what she's become makes her sad and she gasps and gasps and vomits all the blood she's consumed, hyperventilating and choking and crying (her tears are blood now).
But she's just killed fifteen people and she's coated in sixteen people's blood (including her own).
"Thalia, Thalia, please stop," She turns around swiftly.
"Luke?"
And she runs with her superhuman speed, because she's missed him, oh, she's missed him. Her hands grasp his face and why is he here? But no, that doesn't matter, not when he's here. Her bloodied hands touch his face and neck and chest and he buries his face in her neck. That blood shouldn't be there. She's awful, she's completely and utterly fucking disgusting, how could she have done this? She wants so badly to apologize.
"Please stop," he whispers. Of course she will. She'll never do it again. So she nods.
"I'm in love with you."
(She says this every time. He cries for her every time.)
