Not really a secret; again, it's all explained in a story I've sorta started and haven't finished yet. I do that a lot. Scooter is a nickname (in fact, I have a joke planned with Pepe on that) and while most people call him by said nickname, if Piggy needs to have a serious discussion with him (as she did last chapter), she will call him by his name. She's done it several times in the Pool Hall series At this point - in my universe at least - she is the only person (outside of family) that actively does call him that. It's one of those subtle things that points to the fact that the two have a more familiar (family) relationship than that of a friendship. I thought up a nice little speech where Scooter even states that he cares about them (K & P) than an employee should probably care about his employers. But, again, that's a tale for another day. Anyway, I might get some writing done during lunch, so maybe I'll have something up for you.
