Prince Caspian???

I haven't seen the film, but in one trailer i thought I saw Susan and Prince Caspian kiss. I don't think that happened in the book.....I read it when I was 10......what the h3ll?? Did they add that stupid crap in? Oh and did they remove Peter and Susan from Narnia, because I know (from book) that Aslan tells the 2 eldest that they will never return to Narnia again. So if they make the other books into movies, Peter and Susan should not be there.
