well it's been a long time

In Thomas Foster's, How To Read Literature Like A Professor, Mr. Foster mentions the fact that every story and every character are connected in one way or another. He calls it "intertextuality" (no joke.). I find this concept very interesting. He claims that no one really intends for intertextuality to happen, but it does. Now, I could get into how perhaps this is only because the human brain can only think on certain levels, no matter how smart you are, and how all minds are alike in some way generally, but I won't. My point is,

Do my characters remind you of characters in other books you've read? Who were they? Is it a good connection, or a bad one?
