Been looking for a couple of stories where a girl ends up transformers. One of them was after an accident of some sort and she sorta took the place of her tranformers universe self that died. I remember something about 'rule of three' or something that she used as a reason to refuse sharing information with the Autobots. SOmething about how if she shared information and prevented a bunch of deaths, even more people would die.
The other story I read ages ago and I don't really remember much other than this girl ending up in transformers and drawing the attention of the Autobots, and to keep an eye on her Optimus took the form of a double decker bus. There was also something about some old ladies talking about Prime's holoform on the bus... something about wanting to see him in a leopard print speedo or something?
