In the first couple of routes Cody was simply passively more horny because of Scribbles without much of an indication, in Scribbles' route this horniness is actually visible and it actively affects him, so it will not be present in any other route, or even chapter 2.
Scribbles is only narrator in his own route, he won't be one again, but he might be a bit more included in Cody's thoughts.
Therium won't be a stalker anymore in chapter 2.
