Blade was trying to stop thinking about all his problems, training with his sword at 3:00 am. He was making so much noise breaking things that he ended up waking you up.

He was just too concentrated on his smooth movements that you could easily sneak in the training room and surprise him from behind. As you arrived right behind his muscular back, you gave him a little pat.

His reflexes made him bring his sword up to your neck, but then, when he noticed it was you, he immediately pulled it away

"It's late, kid.. go to sleep."
