I was talking about the tone too. For example, if your character says "yeah", you have to add, in my opinion, if it's said in a rather joyful, an enthousiastic, a bored or even a sarcastic way, as it can have a really different meaning depending on the tone. :)

And of course if you use a character from the show, you should keep his personnality as well...
