He instantly grinned the moment she relented, because that was what he was going for. Good. His sister was susceptible to his abilities to make people feel bad. It made him feel good for a moment, that he still had the ability as the little brother to do that. Even if he hated to bring it out for obvious reasons. But right now it seemed like a great time to do it.
He hugged her back to show that things were good with them, hoping that she was really alright and wouldn't freak out the moment she got home. "Thanks, sis. I hope that bubble bath and cookies treat you right," he said with a laugh as he waved back to her before she made her way out the door.
Now he just hoped his sister didn't freak out for no reason.
