I found out thanks to google xD (stupid me xD), of COURSE film would darken after the developer bath if not rinced.
In case any holo beginner would ask the same question someday, i'll put a couple lines of the explanation :
The developer bath only reacts with exposed silver-halides in the film.
Therefore, after it has developed the exposed silver-halides, the remaining white/transparent parts are still light-sensitive, meaning that if you do not rince the developer chemical which are on it it will continue processing the film whenever some light comes and expose the silver-halides.
So, yes, rincing after developer bath is absolutely necessary (I even read about "stop bath" where an acid bath is used to competely disable the developer agent, which requires alcaline environnement to work).
The bleaching (also referred as Fixing) step is also mandatory to clean the film/plate out of any remaining light-sensitive material !
