Imperative

"-and it's absolutely crucial that you watch my footwork on this maneuver…"

Percy had zoned out, which probably was not a good idea, given that he was in the middle of training some of the campers that were more inexperienced with swords. Though, that didn't really faze him, as the son of Apollo that he was sparring with couldn't even touch him while he was standing still.

No, the fact that an untrained minor was swinging a sword not five feet away from him barely registered. Percy had become lost in blonde waves (the very best kind, in his opinion, and that was saying something), never-ending legs, and deep, deep gray eyes. She looked at him from across the arena and waved from where she was training another group of new demigods, a bright smile plastered on her face.

Percy grinned back stupidly before feeling a tap on the shoulder. He heard metal shatter and whipped around suddenly to see Timothy Sung holding the hilt of his sword, standing in the shattered remains of the blade.

"Sorry Percy, I didn't mean to actually, hit- why did the sword break anyway?"

He shrugged, not really inclined to answer, and looked back at Annabeth. The girl was laughing while her group of kids was staring at him in awe.

When she stopped heaving from laughter, Annabeth turned to her group and said, "That is why it's imperative to keep your eyes on the battle. If you weren't invulnerable like Seaweed Brain over there, you'd be sliced to ribbons."
