Chaos Unraveled OOC Community

Okay, so my character comes from modern earth, and is very hip with new subcultures and such, it's the only thing keeping her 2,000 year old self sane. So presumably my character reads books and goes to the movies and has an interest in manga and plays World of Warcraft. So does she know that some of these people are from stories? Does she recognize that fact? Or is that sort of meta level recognition not allowed?

AND, if it is, is she allowed to use that information if she's happened to have read that book/seen that movie in particular?

I am thinking specifically of Scrubs, Transformers, and Death Note here. If my person tells another person that they're a character in a book she read, how is that going to pan out?

*is confused*

How should I address this?
