Dani stopped and watched him try to build. Taking note of his shakey hands, she guessed the kid was a great fighter since his gunpla assembly skills didn't seem top notch. The female let out a sigh and put down her tools. She rolled herself closer to him and grabbed his hands. "Take a few deep breaths and close your eyes, just focus on being calm and then cut a little bit away from the plastic of the part." she said, helping guide his hands to where they had to be. It also appeared that he didn't have much choice since he could tell that her hands and arms were more akin to the jaws of life than human body parts. 

She helped him clip a single part out, then showed him what to do. "You go in closer with the snippers the second time around, cutting it almost flush with the plastic, leaving a teeny tiny bit to sand down." she explained, still guiding his hands until the part was clipped down. Then the girl had him pick up sand paper before having him set to work grinding down the remaining stubs. "Good, now look at the part." she said, the one that she helped him with looking damn good.
