You see, I want to make it so no matter who is talking, you know who it is. You just read the line and immediately know, "oh that is from ____ because he speaks like _____." One character talks in "thesaurus abuse"; if there is a 6 syllable word he can use instead of one, he will use it. Now when he is hurting, that stops and he talks normally. Another character is more deadened to it all. She is seemingly emotionless. Instead she has tattoos that change between lightning, skulls, flowers, etc depending on her mood, even if she doesn't show it. Is this stuff too subtle?
