Forum:Students from HP3-PS2 / HP6-NDS

Why are there two articles for some characters from HP3 on PS2 or HP6 or NDS (for example: Irving Cram (I) and Irving Cram (II)) while others are in one article (Dennis Aldermaston, Rhonda Fladbury)? It's clear that developers taken all names of the third game for reuse them in the sixth. I guess it's because these characters are prefects but I have some arguments: What do you think about that?

 * Take Irving Cram I and II for example: they are both the same name, the same house and the same function in game: they limit the progression of the player.
 * A prefect can repeat a year. A prefect is generally a student with a good behavior (and eventually good notes), but that doesn't prevent him to repeat a year (he can have an impeccable school year but fail his OWLs because of stress / it can also become a brilliant one year (fifth) and bad the next year (sixth, seventh) (exemple : James Potter was wicked in his fifth year but better after, the reverse is also possible).
 * It's just a game, not a book from J.K. Rowling: developers just wanted to take names without think about school years, it should not be too serious about that, it's just a gameplay element.
