She's not sure what it is.
A premonition? No, that's not right. Not really. It's much, much more real than that. It's a shiver down her spine and it's a cord, a rope, attached right to the small of her back, opposite her navel. It's a rope, attached to her back, and it's pulling her.
To him.
Now, she's felt a pull towards Percy for a while now but this one is different because it's not in a, he's- my- best- friend- but- kinda- cute- hey- maybe- I- don't- wanna- kill- him type way but in an, oh- my- gods- this- boy- I- might- love- is- in- mortal- danger type way.
Annabeth has always been reasonable and that part of her is saying, don't be an idiot, he's invincible. He can't get hurt.
But images fly past her eyes, of Achilles getting shot in the heel and of Percy lying in the bed after the scorpion attack and of a silly little boy who drooled too much who just might be her ticket to the quest she always wanted. Then she sees him dead on the ground and Luke's- Kronos's- laughing eyes and screw being reasonable.
He's in trouble and she's not going to let him die because she was being reasonable.
Ethan Nakamura's knife comes down but it doesn't hit its intended target. Instead it breaks through her arm and she cries out in pain, falling to the ground just as he calls her name and he's alive.
She can barely decipher what's happening. Ethan Nakamura falls to the ground but he isn't dead and Percy's eyes are blazing. He forces the army away from her and Kronos- Luke- studies them.
"Interesting."
There's nothing interesting about it- he had been in trouble and she had saved him. She'd do it again, jump in front of a hundred knives for him.
"Bravely fought, Percy Jackson. But it's time to surrender... or the girl dies."
"Percy, don't," she pleads. He has to keep fighting, he can't surrender or else it would have been for nothing. He looks at her blood stained shirt and her heart drops because the stupid Seaweed Brain is going to try and save her.
"Blackjack!"
The pain is so intense she doesn't clue in until she's picked up by her armour and flown over, her last image of him fighting and yelling and very much alive.
