The familiar icy crawl made its way to form an icy blue gas that calmly exited Danny's mouth. He was about to stand and excuse himself from Lancer's class, as usual, but then he remembered the offer of his parent's help. He feels guilty at the thought he might be interrupting their work, but then he thought of the experience his parents could get. They weren't terrible ghost hunters, they're just a little bit unaccustomed to how ghosts are supposed to be fought during the battle.
He, as subtle as he could, pulled out his phone - even as far as turning it invisible. He sent a quick message to his parents, and in a matter of minutes, the Fenton Assault Vehicle was just outside of the school.
Danny caught a glimpse of them fighting the box ghost, and he could say that they did a pretty good job and did little harm to the ghost.
He turned his attention back to Lancer's class and took notes. It felt good being a normal kid for once and not have to skip class.
