One afternoon she rushed to his place, so eager for him that she hadn't even changed her coveralls from working with Paj in the shop. She didn't knock anymore, just let herself in. She made her way through the house until she found him up in his room, stretched out on the futon that was positioned underneath the loft that served as his bed. He looked up at her, surprised, and suddenly lustful at the sight of her. "Nice boiler suit," was all he said, but he'd left it mostly on her while he thrust himself to completion in her mouth, her face still streaked with oil and engine dirt.

That was the first time he'd really pushed her for an alternate solution, and it coincidentally aligned with the resolution of her problem with Pythagoras. She decided to wash away all the dirt and grime in the little shower off of David's loft bedroom and when she came out, wearing a towel turbaned around her hair and nothing else, she found him standing there, fingering her coveralls thoughtfully.

"Want a pair?" She teased him, knowing he didn't know the difference between a fuel injector and a timing belt. "You could come help me put the finishing touches on Stuie. He's almost street legal now that he's got a new muffler system."

"Catherine, I'm a bleeding idiot!" David stared at her in awe, probably the first time he'd looked at her naked without a hint of lust in his eyes.

"Huh?" She flipped the towel off her head and quickly dried her hair with it.

"You're a kinesthetic learner. Of course you are. How thick can I bet?" He shook his head, laughing to himself. "You can take an engine apart with one hand tied behind your back, but you can't learn Pythagoras' theorem? What's wrong with that picture?"
