...if your character never actually mentions the other character's name? Still in the opening of my nano, and have one character make an of hand reference to, "The Brushtail's pet digger," which as I think about it isn't really a nice way for him to refer to Lady Dorothea Bayard, AKA Aunt Dottie, archaeologist and family black sheep from
jeriendhal's
Terinu fanfic Spin Recovery. He needed to make reference to someone known for studying pre-subjugation history, and hey, what do you know there might not be anyone mentioned in canon so far (that I recall being mentioned) but Dottie fits the bill (and is probably eccentric enough to be known). Which yes, means what I'm working on is also a Terinu fanfic. Or at least set in the same universe, most likely it won't involve any of the major characters.
Although hopefully my characters will be able to avoid running into addiction and loss of limbs like happened in Spin Recovery. Which isn't to say that they'll manage to avoid the involvement of law enforcement. Then again a story without troubles isn't going to be a very interesting story. For someone is going to be a very naughty boy, forcing my main character to take care of things when she'd rather not be on scene at all. ("Troublesome commoners and their silly celebrations, should never have accepted that offer of shore leave to visit home. Could have been in training, or doing paperwork, or getting shot at by pirates instead of this.")
Now to try and actually write past the opening scene...
EDIT: Hurrah, I do believe I now have a title. "The Unquiet Past"
