Fredericks was not pleased. The very fact the captain seemed to listen to the girl just because she was 'right' on one thing was infuriating. Of course, she was a bit right. What he had been having her work on were fine and irrelevant. However, he was annoyed having a girl as an assistant, and one that had got him already in trouble, that he was going to make her time here wasted so hopefully they'd get rid of her again. Besides, she was supposed to obey without question. It didn't matter what he had her do. He could have been wanting to make sure every part worked - you don't want to go up again in case one didn't. Not that that was his intent. 

He looked at the captain wondering how he should reply. The man couldn't do it without him, despite his stubbornness. Fredericks was the mechanic. He knew how to fix it. And if the guy wanted to leave anytime soon, he would have to keep Fredericks on at least until it was fixed - finding another mechanic would be difficult and there was no way the girl would know what to do. She might have gotten lucky but she was an idiot when it came to fixing. 

Yet, there was something there. If he pushed it, he knew he would be gone. The question though, was did he risk it and have the captain come back begging for his help later or did he just go back in and fix what he can? Common sense recommended the latter but a bit of pride pushed the former. He pushed his cap up and looked at the captain. "I just might," he warned. "I did rescue help, and I appreciate it - but she'll be more of a hindrance. I can't work with her. Not all help is good help." He said firmly.
